In today's global business environment, the intense competition, the changing and uncertain conditions, and the increasing customer's requirements are challenges for the companies' operational efficiency and profitability. In this context, companies highlight the importance of supply chain design and its holistic understanding in order to achieve and sustain competitive strengths. This book analyses supply chains as complex systems, whose performance is characterized by their structural configuration and emergent behaviour. The author analyses the supply chain structure and behaviour within the scope of complexity science. He focuses on supply chain complexity by means of a literature review and an empirical research, which give insights into the impact of complexity on supply chain performance. Moreover, within this book the supply chain is modelled as a complex system by considering the non-linear relationships of its geo-positioned elements. Finally, an agent based model is developed for the generic supply chain simulation, which allows assessing the impact of complexity on supply chain performance and characterizing the behaviour of supply chain designs. The materials presented in this book contribute to the understanding and management of supply chain complexity. This work complements existing complexity frameworks with a holistic analysis of complexity's impact on the performance of supply chain participants and their network. The findings of this work are relevant for researchers interested in characterizing supply chain phenomena by enabling them to model supply chain structures and to simulate their emergent behaviour. Practitioners can benefit from the provided model and simulation platform by allowing them to dynamically assess the performance of their supply chain designs and strategy definitions. By these means, they improve their decision-making and business profitability. In all, this book contributes towards the development of artificial intellig

An extensive review of the current literature on supply chain management research shows that, traditionally, a supply chain is typically viewed as a hierarchical structure in which the information and materials flow in a vertical point-to-point fashion and each individual at a level is independent and does not interact with others horizontally. The methodologies often found are mathematical deduction or induction with, sometimes, numerical simulation or empirical data analysis to support the theories. These traditional approaches are very powerful and efficient in solving many problems. However, they are inadequate in the areas that the agent based modeling is capable of. These areas include capturing emergent phenomena; providing a natural description of a supply chain system; and being flexible (scalable and adaptive). This dissertation investigates the supply chain system in a way different from the traditional approaches. Our view of a supply chain is a hierarchical structure with horizontal layers, in which exist interactions between the members (retailers, in our case, who exchange information and stocks). We no longer treat the system as point-to-point, but point-to-layer relationships. We use the agent based modeling to represent in a more natural way the individual interactive entities in the supply chain system and investigate the emergence due to the interactions between these entities. In this dissertation we have demonstrated that interactions between retailers have plausible consequences on the supply chain performance. In particular, we look at the total average costs at the supplier side and find significant improvement in cost reduction as the interactions among the retailers increase. Through the external validation, we confirm that the new agent based modeling method produces the exact results as those from the previous research with traditional approaches. We use agents to represent the firms in the supply chain and program the behaviors for each agent by applying the existing mathematically proved functions. We also use the agents to demonstrate the bullwhip effect. We have shown that without information sharing, the supplier needs to periodically update the mean and variance of demand based on observed demand data through orders received from retailers, then the variance of the orders placed by the supplier will be greater than that by the retailer and in turn the demand. More importantly, providing sufficient information of the underlying demand to the supplier can significantly reduce this increase in variability.

The increasing interest about sustainability in supply chains highlights the influence of economic, social and environmental factors. The interaction of these factors generates an emerging complexity that is far beyond the 'sum of the parts'. This is why new tools are required to deeper understand and manage this complexity. In this ongoing work, we focus on supply chain; in particular, as our ultimate goal, we focus on food mass purchasing consortium (MPC) market because of the availability of literature and data on this specific topic. The main need of chain actors is to maintain competitive advantage. In this scenario, the typical questions arising in this environment are the following. What are the market opportunities for each actor position? Could we improve the chain performance by a more clever exploitation of the available information? How much information should be shared among actors? We propose an agent based modeling (ABM) approach to study and identify the supply chain weaknesses by modeling its structural evolution over time. Our approach can provide answers to the previous questions. We believe this approach is promising since it could represent a valuable tool in (i) understanding supply chain processes and (ii) in testing social, economical and political strategies in order to achieve better sustainability models.

Supply Chain Simulation allows readers to practice modeling and simulating a multi-level supply chain. The chapters are a combination of the practical and the theoretical, covering: knowledge of simulation methods and techniques, the conceptual framework of a typical supply chain, the main concepts of system dynamics, and a set of practice problems with their corresponding solutions. The problem set includes illustrations and graphs relating to the simulation results of the Vensim® program, the main code of which is also provided. The examples used are a valuable simulation tool that can be modified and extended according to user requirements. The objective of Supply Chain Simulation is to meet the demands of supply chain simulation or similar courses taught at the postgraduate level. The “what if” analysis recreates different simulation scenarios to improve the decision-making process in terms of supply chain performance, making the book useful not only for postgraduate students, but also for industrial practitioners.

"Supply Chain Event Management (SCEM)" is one of the major topics in application-oriented Supply Chain Management. However, many solutions lack conceptual precision and currently available client-server SCEM-systems are ill-suited for complex supply networks in today's business environment. Agent-based proactive information logistics promises to overcome existing deficits by providing event-related information to all participants in the distributed environment. Hence, follow-up costs of disruptive events are significantly reduced for all network participants and performance of a supply network is increased. In this book a thorough analysis of the event management problem domain is the starting point to develop a generic agent-based approach to Supply Network Event Management. The main focus lies on practical issues of event management (e.g., semantic interoperability) and economic benefits to be achieved with agent technology in this state-of-the-art problem domain.

Supply chains are increasingly complex as companies branch out into newer products and markets. In many cases, multiple products with moderate differences in performance and price compete for the same unit of demand. Simultaneous occurrences of multiple scenarios (competitive, disruptive, regulatory, economic, etc.), coupled with business decisions (pricing, product introduction, etc.) can drastically change demand structures within a short period of time. Furthermore, product obsolescence and cannibalization are real concerns due to short product life cycles. Analytical tools that can handle this complexity are important to quantify the impact of business scenarios/decisions on supply chain performance. Traditional analysis methods struggle in this environment of large, complex datasets with hundreds of features becoming the norm in supply chains. We present an empirical analysis framework termed Scenario Trees that provides a novel representation for impulse and delayed scenario events and a direction for modeling multivariate constrained responses. Amongst potential learners, supervised learners and feature extraction strategies based on tree-based ensembles are employed to extract the most impactful scenarios and predict their outcome on metrics at different product hierarchies. These models are able to provide accurate predictions in modeling environments characterized by incomplete datasets due to product substitution, missing values, outliers, redundant features, mixed variables and nonlinear interaction effects. Graphical model summaries are generated to aid model understanding. Models in complex environments benefit from feature selection methods that extract non-redundant feature subsets from the data. Additional model simplification can be achieved by extracting specific levels/values that contribute to variable importance. We propose and evaluate new analytical methods to address this problem of feature value selection and study their comparative performance using simulated datasets. We show that supply chain surveillance can be structured as a feature value selection problem. For situations such as new product introduction, a bottom-up approach to scenario analysis is designed using an agent-based simulation and data mining framework. This simulation engine envelopes utility theory, discrete choice models and diffusion theory and acts as a test bed for enacting different business scenarios. We demonstrate the use of machine learning algorithms to analyze scenarios and generate graphical summaries to aid decision making.

Decision makers in large scale interconnected network systems require simulation models for decision support. The behaviour of these systems is determined by many actors, situated in a dynamic, multi-actor, multi-objective and multi-level environment. How can such systems be modelled and how can the socio-technical complexity be captured? Agent-based modelling is a proven approach to handle this challenge. This book provides a practical introduction to agent-based modelling of socio-technical systems, based on a methodology that has been developed at TU Delft and which has been deployed in a large number of case studies. The book consists of two parts: the first presents the background, theory and methodology as well as practical guidelines and procedures for building models. In the second part this theory is applied to a number of case studies, where for each model the development steps are presented extensively, preparing the reader for creating own models.
