Measuring performance in supply chain networks
Today, the formation of increasingly complex supply chain networks sets new demands for performance analysis. Performance analysis needs to look beyond the narrow perspective of the focal firm and measure performance not only from a financial perspective. This thesis illustrates how the network …

Polynomial policies in supply chain networks
… periodic-reviewed inventory control problem in supply chain networks with uncertain demand so as to minimize the overall cost of the system over a fixed planning time horizon. In such problems, one seeks to optimally determine ordering quantities at different stages in time. We investigate the …

Robustness of complex supply chain networks to targeted attacks
… this thesis, we study the robustness of complex supply chain systems from a network science perspective. Through the simulation of targeted attacks to nodes and edges using different hierarchical measures from network science to select the most relevant components, we evaluate the extent to which …

An investigation into Indian apparel and textile supply chain networks
The activities of the Indian clothing industry supplying Western markets have been investigated, with particular reference to identifying where improvements could be made to supply chain management. Focus group discussions, case studies and questionnaire analysis established that long lead-times in …

Reengineering the order fulfillment process in supply chain networks: A multiagent information system approach
… improve the order fulfillment process (OFP) in supply chain networks (SCNs). An order fulfillment process starts with receiving orders from customers and ends with delivery of finished goods. The order fulfillment process is complex because it is composed of several activities, executed by …

Social and engineering perspectives on optimal farm management and reliable grain supply chain networks
… understanding of strength and weakness of grain supply chains provide opportunities to plan a reliable and robust food networks, thereby assisting farm management and reducing post-harvest losses. Thus, the overall objective is developing a framework to support farming decisions that enhance farm …

Supply chain responsiveness for a large retailer
… retailer underwent a large, complex multi-year supply chain network transformation. This transformation resulted in significant savings in logistics costs. Additionally, the regional distribution center that was introduced as part of this transformation as a new node between the supplier and the …

Inbound container queuing optimization model for distribution centers
… multi-national retailers have massive, worldwide supply chain networks which move product from a supplier to the end consumer. During the product's transit from a factory to a regional distribution center, customers may change or cancel their order, or the planned arrival date of the product at …

Improvement on service part supply chain with centralized management and global optimization
… performed under the supervision of the global supply chain department of InFocus Corp. The company is having high service costs in the Asia Pacific region and desperate to lower the cost in the reverse supply chain and to improve the service level to its customers. In this thesis report, …

Outbound transportation collaboration- Do It Yourself (DIY)
… of the synergies that may exist in their supply chain networks. Such collaborations can be orchestrated through a 3PL or by the companies themselves via a Do-It- Yourself (DIY) approach. Collaboration can be active or passive. Active collaboration is when shippers plan their shipments with …

Transportation context of Latin American logistics
… Penetrating such a market requires a taut supply chain and while there are many facets to any supply chain, we here focus on the transportation aspect and build the Latin American context surrounding it and affecting logistical decisions and paradigms. By exploring the unsuccessful and …

Applications of robust optimization to queueing and inventory systems
… we propose methods to compute (s,S) policies in supply chain networks using robust and stochastic optimization and compare their performance. Our algorithms handle general uncertainty sets, arbitrary network topologies, and flexible cost functions including the presence of fixed costs. The …

Evaluation of automated storage and retrieval in a distribution center
… manufacturers to evaluate their existing supply chain networks to meet two- and one-day shipping from their distribution centers (DC). This thesis evaluates speed and execution improvements using automated storage and retrieval systems (ASRS) in DCs. Adopting ASRS can provide the essential …

Robust Cross-dock Location Model Accounting for Demand Uncertainty
… optimization models to locate cross-docks in supply chain networks. Cross-docks are a type of intermediate facility which aid in the consolidation of shipments, in which the goods spend little or no time in storage. Instead, the goods are quickly and efficiently moved from the inbound trucks …
