Business Systems and Analytics Faculty Work

Many companies face challenges in reducing their supply chain costs while increasing sustainability and customer service levels. A comprehensive framework for a sustainable closed-loop supply chain (CLSC) network is a practical solution to these challenges. Hence, for the first time, this study considers an integrated multio-bjective mixed-integer linear programming (MOMILP) model to design sustainable CLSC networks with cross-docking, location-inventory-routing, time window, supplier selection, order allocation, transportation modes with simultaneous pickup, and delivery under uncertainty. An intelligent simulation algorithm is proposed to produce CLSC network data with probabilistic distribution functions and feasible solution space. In addition, a fuzzy goal programming approach …

Exploring The Influence Of Industry 4.0 Technology On Buyer-Supplier Relationships (Supplier Transparency) And Supply Chain Agility, Honey Zimmerman

Dissertations

Constantly evolving technologies enable supply chains around the world to thrive and become progressively more sophisticated and responsive. Industry 4.0 (I4.0) technologies connect supply chain networks like never before. Still, anecdotal evidence suggests that few firms have implemented such technologies enterprise-wide. Therefore, to investigate the value created from the implementation of such technology, the focus of this study was on buyer-supplier relationships (BSR) and firm supply chain agility (FSCA) in the context of I4.0 technologies. Using mixed methodologies within a single-case study, we set out to answer the research question: Does I4.0 technology influence buyer-supplier relationships and firm supply chain …

Forecasting Demand For Optimal Inventory With Long Lead Times: An Automotive Aftermarket Case Study, Chris Anderson

Dissertations

Accuracy in predicting customer demand is essential to building an economic inventory policy under periodic review, long lead-time, and a target fill rate. This study uses inventory and customer service level as a stock control metric to evaluate the forecast accuracy of different simple to more complex predictive analytical techniques. We show how traditional forecast error measures are inappropriate for inventory control, despite their consistent usage in many studies, by evaluating demand forecast performance dynamically with customer service level as a stock control metric that includes inventory holdings costs, stock out costs, and fill rate service levels. A second contribution …

How Random Incidents Affect Travel-Time Distributions, Melike Baykal-Gürsoy, Andrew Reed Benton, Pedro Cesar Lopes Gerum, Marcelo Figueroa Candia

Supply Chain Management

We present a novel analytical model to approximate the travel-time distribution of vehicles traversing a freeway corridor that experiences random quality of service degradations due to non-recurrent incidents. The proposed model derives the generating function of travel times in closed-form using clearance time, incident frequency and severity, and other ordinary traffic characteristics. We validate the model using data from a freeway corridor where weather events and traffic accidents serve as the principal causes of service degradation. The resulting model is equivalent in performance to widely used methodologies while uniquely providing a clear connection on how incidents affect travel time distribution. …

Resource Capacity Requirement For Multi-Terminal Cooperation In Container Ports, Byung Kwon Lee, Mei Wan Low

Research Collection Lee Kong Chian School Of Business

Capacity sharing among neighboring terminals offer a means to meet increasing or unexpected demand for cargo-handling without additional capital investment. This study proposes a model for capacity requirement planning of major resources, such as quay cranes (QCs), storage space, and gate, in multiterminal port operations where demand is time dependent. A resource profile simulation is run to generate random events across the terminals and estimate the capacity requirement in the form of workload distributions on port resources over time-shifts. The effects on workload requirement, arising from multiterminal cooperation, are subsequently evaluated in consideration of different container flows among terminals. Experimental …
