Long Short-Term Memory (LSTM) Networks for Forecasting

Long Short-Term Memory (LSTM) networks are a type of recurrent neural network (RNN) designed to effectively learn and remember long-term dependencies in sequential data. LSTMs address the limitations of traditional RNNs, which struggle with long-term dependencies due to issues like vanishing and exploding gradients. 

Architecture of LSTM Networks

LSTMs have a more complex architecture than standard RNNs. The key component of an LSTM is its memory cell, which maintains information over long periods. Each LSTM cell contains several gates that regulate the flow of information:

1. Forget Gate (𝑓_𝑡): Decides what information to discard from the cell state.
2. Input Gate (𝑖_𝑡): Determines which new information to add to the cell state.
3. Cell State (𝐶_𝑡): Represents the memory of the network.
4. Output Gate (𝑜_𝑡): Decides what information from the cell state to output.

These gates are controlled by sigmoid and tanh activation functions, which output values between 0 and 1 to modulate the information flow.

LSTM Equations:

LSTM Cell Structure

Here's a diagram representing the structure of an LSTM cell:

 

1. Forget Gate: This gate uses the sigmoid function to decide which parts of the cell state 𝐶_𝑡−1 to forget.
2. Input Gate: It controls which values to update with new information. The sigmoid layer decides which values to update, and the tanh layer creates new candidate values ​ to be added to the cell state.
3. Cell State Update: The cell state 𝐶_𝑡 is updated by combining the old cell state (scaled by the forget gate) and the new candidate values (scaled by the input gate).
4. Output Gate: This gate determines the output of the LSTM cell. It first uses a sigmoid function to decide which parts of the cell state to output, then applies the tanh function to scale the cell state before multiplying by the output gate's result.

Applications of LSTMs

LSTMs are widely used in various fields due to their ability to capture long-term dependencies:

• Natural Language Processing (NLP): For tasks like machine translation, text generation, and sentiment analysis.

Handling computational complexity, data requirements, and interpretability 

To handle computational complexity, it would be necessary to optimize the model architecture. Depending on the context, simple versions of LSTMs (e.g., Vanilla LSTMs, Gated Recurrent Units) might suffice and they are less computationally intensive. One could start with few layers and then add complexity as needed. Dropout regularization can help in preventing overfitting as well as computational load during training. The models used for LSTM can be compressed using techniques such as quantization (i.e., reducing the model’s precision from floating points to fixed point representation) and pruning (i.e., removing connections in the network that are not significant).

While reduction in complexity by optimizing model architecture and model compression will be helpful, it is still going to be important to deploy efficient hardware and software (e.g., high performance computing that utilize Graphics Processing Units (GPUs) and Tensor Processing Units (TPUs) and facilitate parallel processing. Firms can also take advantage of distributed computing frameworks (e.g., Apache Spark, TensorFlow’s distributed computing) that allows for models to be trained across multiple nodes.

For managing data requirements, steps such as normalization of the data, using synthetic data to augment training set, integrating data from external sources that might be relevant for forecasting, using batch processing and mini-batch gradient descent (specifically, to effectively deal with large datasets), and dimensionality reduction (e.g., using Principal Component Analysis to reduce the number of features) can go a long way.

To improve interpretability, one could implement attention mechanisms within the LSTM architecture to highlight which parts of the input sequence the model is focusing on during prediction or could use saliency maps to visualize the importance of different input features and time steps in the prediction process. There are also some methods such as help in understanding of each feature to LSTMs prediction (e.g., SHAP – Shapley Additive Explanation) and to explain individual predictions by approximating the LSTM model with a simpler interpretable model locally (e.g., LIME - Local Interpretable Model-agnostic Explanations). Sometimes it is also helpful to integrate multiple models, e.g., using LSTM + Decision Trees or LSTM + Linear Models so as to have clarity on the predictions.

As is always the case, proper documentation and reporting protocols can ensure that the knowledge gained by implementing these tools are preserved and enhanced as a company continues the journey of using these tools.

Artificial Intelligence driven Supply Chain Planning Algorithms

AI-driven supply chain planning leverages complex algorithms to enhance efficiency, accuracy, and responsiveness across various supply chain functions. Organizations need to not only follow systematic steps to achieve performance outcomes, but also be cognizant of factors that present challenges in reaping associated benefits. 

The foundation of AI-driven supply chain planning lies in Data Collection and Integration, i.e., gathering vast amounts of data from diverse sources. Internal data sources include sales history, inventory levels, production rates, order fulfillment data etc. On the other hand, external data sources include market trends, supplier performance, economic indicators, weather conditions, social media sentiments etc. Data is integrated into a centralized system, often facilitated by cloud computing, to create a comprehensive dataset for analysis.

The next step involves Data Preprocessing to ensure quality and consistency before feeding the data into AI algorithms. In this stage the data is cleaned by removing duplicates, correcting errors, and handling missing values. Normalizing helps in scaling the data to a consistent range to improve algorithm performance. Categorical data is often transformed into numerical values using techniques such as one-hot encoding.

Feature engineering involves selecting and transforming relevant data features to enhance the predictive power of the model. Key variables that have significant impact on supply chain performance (e.g., lead times, demand patterns) are identified and new features are derived from existing data, such as calculating average lead times or seasonal demand variations.

After these initial steps are undertaken, Model Selection ensues depending on the specific supply chain task. For instance, demand forecasting calls for time series models (e.g., ARIMA, Prophet), regression models (e.g., linear regression, gradient boosting), and deep learning models (e.g., LSTM networks). Reinforcement learning models are used for inventory optimization where these models learn optimal stocking policies through simulations. Optimization algorithms (such as genetic algorithms, ant colony optimization) and neural networks are used for route optimization so that efficient delivery routes can be identified.

Once the models are selected, using historical data the Training phase enables the algorithm to learn patterns and relationships within the data using historical data, adjusting its parameters to minimize prediction errors and the Validation phase helps in evaluating the model's performance on a separate validation dataset to ensure it generalizes well to new data. 

Once trained, the AI models help with Prediction and Optimization of supply chain operations. These could include such areas a demand forecasting (predicting future sales based on historical data and external factors), inventory management (recommending optimal inventory levels to balance holding costs and service levels), production scheduling (allocating resources and scheduling production runs to meet predicted demand efficiently), logistics and distribution (optimizing delivery routes, shipment schedules, and transportation modes to minimize costs and delivery times) and others.

AI algorithms then enable Real-Time Decision-Making by continuously analyzing incoming data and updating predictions and recommendations. With adaptive learning, the models adapt to new data, improving their accuracy over time. Automated adjustments help the system to automatically adjust supply chain parameters (e.g., reorder points, production schedules) based on real-time insights.

The final step in AI-driven supply chain planning involves a feedback loop for Continuous Improvement. Through performance monitoring KPIs (e.g., order fulfillment rates, inventory turnover) are tracked to measure the effectiveness of AI-driven decisions. Periodically model retraining with new data helps in maintaining and enhancing performance. Running "what-if" scenario analysis prepares a firm for potential disruptions and optimizes contingency plans.

Notwithstanding these step-by-step approach for using AI algorithms for supply chain planning and their associated advantages, many firms fail to reap those benefits. These challenges often stem from several key factors. Many companies struggle with the quality and integration of data from disparate sources within their supply chain. Inconsistent or incomplete data can lead to inaccurate predictions and suboptimal decision-making. For instance, if historical data is incomplete or inconsistent, AI algorithms may produce unreliable forecasts, impacting inventory management and demand planning. As an example, a multinational consumer electronics company implemented AI-driven demand forecasting software to optimize inventory management. The software struggled with integrating data from various retail partners, resulting in inconsistent demand forecasts. Due to this shortcoming the company experienced issues with inventory levels, leading to excess stock in some regions and stockouts in others, impacting profitability and customer satisfaction.

Companies face difficulties in implementing and fine-tuning complex AI models. These algorithms require specialized expertise in machine learning and data science to develop and maintain. Without sufficient internal expertise or resources, companies may struggle to effectively deploy AI-driven solutions and optimize them for their specific supply chain needs. Resistance to change within organizations can hinder the successful adoption of AI-driven supply chain planning. Employees may be reluctant to trust AI recommendations over traditional methods or may lack the necessary training to interpret and act upon AI-generated insights. Without buy-in from key stakeholders and adequate change management strategies, companies may fail to leverage AI's full potential. For example, a global pharmaceutical company adopted AI-powered supply chain optimization tools to streamline logistics and reduce costs; however, middle management and operational teams were resistant to AI recommendations, preferring traditional planning methods. Despite the potential for cost savings and efficiency improvements, the company failed to fully realize the benefits of AI, resulting in missed opportunities for operational optimization.

The upfront costs associated with implementing AI-driven supply chain solutions can be substantial. Companies may struggle to justify these investments without clear, measurable returns on investment (ROI). Moreover, accurately estimating the ROI of AI initiatives can be challenging due to factors such as implementation costs, ongoing maintenance, and the complexity of measuring intangible benefits like improved decision-making.

Integrating AI-driven algorithms with existing legacy systems and processes can be complex and time-consuming. Legacy systems may lack the flexibility or compatibility required to seamlessly integrate with AI solutions, leading to operational disruptions and delays in realizing benefits. For example, a leading automotive manufacturer invested in AI algorithms to optimize production scheduling and supplier management. Integration issues arose when attempting to link AI systems with existing ERP platforms and legacy systems. Delays in data synchronization and decision-making processes affected production timelines and supply chain visibility, impacting overall operational efficiency.

In industries with stringent regulatory requirements or ethical considerations, implementing AI-driven supply chain algorithms may raise concerns about data privacy, algorithm transparency, and compliance with regulations. Companies must navigate these challenges to ensure that AI solutions comply with legal and ethical standards while delivering operational benefits. For example, a global food and beverage conglomerate implemented AI algorithms to optimize its supply chain, including procurement, production planning, and distribution. The AI algorithms used by the company to optimize procurement decisions inadvertently favored suppliers with lower costs, sometimes sourced from regions with questionable labor practices or environmental standards. This raised ethical concerns within the company and among stakeholders, including customers and advocacy groups. Additionally, there were regulatory concerns related to compliance with labor laws, environmental regulations, and fair trade practices in different regions. The ethical and regulatory concerns posed reputation risk since negative publicity and stakeholder backlash affected the company's brand reputation and consumer trust. The company faced compliance issues since regulatory authorities scrutinized the AI algorithms and supply chain practices, leading to potential fines or legal repercussions for non-compliance. The company had to reassess its AI algorithms and supply chain policies to ensure alignment with ethical standards and regulatory requirements. This involved revising procurement criteria, enhancing supplier vetting processes, and implementing transparency measures in supply chain operations.

Overall, addressing these challenges requires a holistic approach that includes improving data quality, investing in AI expertise, fostering a culture of innovation and adaptability, managing costs effectively, ensuring regulatory compliance, and aligning AI initiatives with strategic business objectives. Companies that successfully navigate these challenges can harness the full potential of AI-driven supply chain planning to achieve competitive advantages in today's rapidly evolving market landscape.

Taming the Counterfeiting Epidemic

In a recently published article, we present the findings of our research that suggests that successfully combating counterfeits requires the attention of a broad collection of organizational functions. It works best with a multilayered strategy encompassing diverse methods and engaging the entire organization and its partners. We recommend that organizations tackle counterfeiting with a cohesive plan for identifying, containing, and preventing it. This comprehensive process means routinely keeping tabs on contract manufacturers and charting how products move through the supply chain. It includes scoping out what is for sale in consumer markets, deploying covert markings, reviewing warranty claims, educating customers, and partnering with key agencies and competitors.

While companies may never completely eliminate bad actors from copying products or diverting goods from authorized channels, they can significantly reduce counterfeiters’ market penetration and restore lost revenue. Successful approaches may involve cutting off counterfeiters’ access to markets, eliminating their supply of unauthorized goods, or making a product more difficult to copy. Building on insights from our case studies and discussions with practitioners, we provide details on the three activities that together help in developing a robust action plan comprises: identification, containment, and prevention. Identification helps in gaining Insight Into the extent and nature of the counterfeiting problem. Containment helps in limiting the problem’s spread. And prevention helps in stopping future counterfeit operations before they start

The mutual causality between supply chain disruption and innovation in low-income markets

In a recently published article, my co-author and I argue that low-income markets have unique constraints that trigger the co-evolution of innovation and disruption in such markets. When disruptions occur in global supply chains, and in particular, in low-income markets, they spur innovations that may be necessary to address both existing and potential future disruptions. However, such innovations in turn create disruptions to existing supply chains, and they may also create new supply chains. We highlight the unique opportunities and constraints that exist in the low-income market contexts that result in interesting and unique dynamics between innovation and disruption. Further, we identify the mechanisms through which innovation-disruption mutual causality occurs—as well as the boundary conditions for these mechanisms.

Using several case examples including Chotukool, Lagos, Nigeria Apapa port, MPesa, Momo, E-Choupal, Zipline drone technology, Dabbawallah, Danone South Africa, Kobo 360, Nestlé’s miniaturized “pure water” sachets, Barefoot College, Diagnostics for all, and Haul247 we discuss how disruption and innovation reinforce each other. Our study presents an integrated framework that considers the underlying characteristics of supply chain disruption and innovation. Supply chain disruption is characterized by impact (which can be low or high), probability (which is high), and level of control (which is low). We characterize innovation by considering whether it is affordable, available, accessible, has high level of awareness/relevance, and has low resource requirement. The mutual causality between supply chain disruption and innovation is strengthened by human and social capital that organizations in low-income markets are able to develop and creative resourcing that needs to move from autonomous to directed over time. Our study also emphasizes that weak institutions can paradoxically strengthen the force with which disruption and innovation reinforce each other. In addition to these moderating factors that strengthen the relationship between disruption and innovation, we also discuss the motivations, cognitive and social mechanisms that link supply chain disruptions to innovation, as well as information availability, structural changes and social equity that link innovation to supply chain disruption. The integrated framework presented in the paper is as follows:

This study offers directions for policy makers and managers regarding the macro-level and micro-level factors that influence innovation and disruption, as well as how to navigate the interplay between disruption and innovation in LIMs. It is noteworthy that this interplay can act as both a deterrent and an opportunity. An understanding of how LIM micro-level and macro-level factors influence disruption and innovation should help in decision-making and policy formulation. In addition, this study provides guidance to policy makers to work closely with organizations, as new innovations within these companies help to manage disruptions emanating from LIM constraints, thereby requiring innovative thinking on the policy front as well. Public-private partnerships can ensure that resource-constrained innovations at the organizational level are optimized and strengthened through policy innovations at the macro level.
