Optimizing (S, S) Policies For Multi-Period Inventory Models With Demand Distribution Uncertainty: Robust Dynamic Programming Approaches, Ruozhen QIU, Minghe SUN, Yun Fong LIM 2017 Northeastern University

Optimizing (S, S) Policies For Multi-Period Inventory Models With Demand Distribution Uncertainty: Robust Dynamic Programming Approaches, Ruozhen Qiu, Minghe Sun, Yun Fong Lim

Research Collection Lee Kong Chian School Of Business

We consider a finite-horizon single-product periodic-review inventory managementproblem with demand distribution uncertainty. We formulate the problemas a dynamic program and prove the existence of an optimal (s, S) policy. Thecorresponding dynamic robust counterpart models are then developed for thebox and the ellipsoid uncertainty sets. These counterpart models are transformedinto tractable linear and second-order cone programs, respectively. Weillustrate the effectiveness and practicality of the proposed robust optimizationapproaches through a numerical study.

Conditional Lot Splitting To Avoid Setups While Reducing Flow Time, Jacob V. Simons, Mark E. Kraus, Willis Mwangola, Gerard Burke 2017 Georgia Southern University

Conditional Lot Splitting To Avoid Setups While Reducing Flow Time, Jacob V. Simons, Mark E. Kraus, Willis Mwangola, Gerard Burke

Jacob V. Simons

Previous research has clearly and consistently shown that flow time advantages accrue from splitting production lots into smaller transfer batches or sub-lots. Less extensively discussed, and certainly undesired, is the fact that lot splitting may dramatically increase the number of setups required, making it impractical in some settings. This paper describes and demonstrates a primary cause of these “extra” setups. It then proposes and evaluates decision rules which selectively invoke lot splitting in an attempt to avoid extra setups. For the closed job shop environment tested, our results indicate that conditional logic can achieve a substantial portion of lot splitting ...

Increasing Sustainability In Global Supply Chains, Daniel Stuesse 2017 Western Washington University

Increasing Sustainability In Global Supply Chains, Daniel Stuesse

WWU Honors Program Senior Projects

Increasing stakeholder concerns about sustainability have recently led businesses to consider environmental, economic, and social issues in supply chain management. This three-component approach to sustainability is known as the “triple bottom line.” The triple bottom line was developed in the 1990s with the intention of providing a framework for evaluating organizational economics along with social and environmental impacts. Climate change and resource depletion necessitate improvements to the sustainability of the current global supply chain to avoid the planet becoming unable to meet the needs of future generations. This paper uses the triple bottom line to examine the current sustainability of ...

Is Marketing Still Part Of Supply Chain Management, And Should Marketing Academics And Practitioners Care?, Stephen M. Rutner Ph.D., Charles David Shepherd Ph.D. 2017 Texas Tech University

Is Marketing Still Part Of Supply Chain Management, And Should Marketing Academics And Practitioners Care?, Stephen M. Rutner Ph.D., Charles David Shepherd Ph.D.

Atlantic Marketing Journal

Over the past twenty years Supply Chain Management (SCM) has exploded as both an academic field of study and a critical competency for success in the modern business landscape. From its original conceptualizations Marketing has been seen as a core component of SCM. However, in recent years Marketing appears to play a smaller and smaller role in SCM theory and practice. This paper discusses the evolution of the SCM concept and its relationship with the marketing discipline, and offers a series of questions to guide future research in exploring these trends.

A Supply Chain Coordination Mechanism For Common Items Subject To Failure In The Electronics, Defense, And Medical Industries, Mikhail M. Sher, Seung-Lae Kim, Avijit Banerjee, Michael Paz 2017 Keuka College

A Supply Chain Coordination Mechanism For Common Items Subject To Failure In The Electronics, Defense, And Medical Industries, Mikhail M. Sher, Seung-Lae Kim, Avijit Banerjee, Michael Paz

Michael Paz

Improved production processes, particularly miniaturization, have led to the development and use of non-reworkable items subject to failure in modern production environments. Coordinating supply chains for these items requires cooperation between suppliers and buyers in order to balance ordering/setup and holding costs among system partners. In this paper, we first determine optimal inventory policies for both the supplier and buyer. We then apply the bisection method to develop a mechanism which uses a common replenishment time to coordinate a supply chain consisting of a single supplier and n buyers. By utilizing this optimization framework, we minimize total system-wide costs ...

Strengthening The F&B Purchaser–Supplier Partnership: Actions That Make A Difference:, Judi Brownell, Dennis Reynolds 2017 Cornell University School of Hotel Administration

Strengthening The F&B Purchaser–Supplier Partnership: Actions That Make A Difference:, Judi Brownell, Dennis Reynolds

Judi Brownell

[Excerpt] One of the more intriguing food-service-operation trends of the past few years is the focus on building partnerships between food-service operators (that is, purchasers) and vendors. At the organizational level, companies are shrinking the number of suppliers with which they work and are developing close ties with a few selected partners.1 As we explain in this article, partnerships of this type are advantageous to both food-service operators and their vendors, because the long-term relationships create value and help the food-service operators maintain a competitive advantage.


Supply Risk Mitigation Of Smes Through Leveraging Social Capital: Development And Validation Of A Measurement Instrument, Priyabrata Chowdhury, Kwok Hung Lau, Siddhi Pittayachawan 2017 RMIT University

Supply Risk Mitigation Of Smes Through Leveraging Social Capital: Development And Validation Of A Measurement Instrument, Priyabrata Chowdhury, Kwok Hung Lau, Siddhi Pittayachawan

Siddhi Pittayachawan

Literature on supply risk management has consistently promoted the use of network capital to mitigate supply risk of small and medium-sized enterprises (SMEs). Many scholars in supply chain management have suggested that structural, relational and cognitive dimensions of social capital in both the buyer–supplier network and the network of peers within a cluster can play an influential role in mitigating the supply risk of SMEs. Although research interest in supply risk management through a social capital approach is growing, so far no study has been directed towards the development of an instrument to measure network capital in the context ...

A Decade Of Progress Toward Ending The Intensive Confinement Of Farm Animals In The United States, Sara Shields, Paul Shapiro, Andrew N. Rowan

Housing and Confinement of Farm Animals

In this paper, the Humane Society of the United States (HSUS) farm animal protection work over the preceding decade is described from the perspective of the organization. Prior to 2002, there were few legal protections for animals on the farm, and in 2005, a new campaign at the HSUS began to advance state ballot initiatives throughout the country, with a decisive advancement in California (Proposition 2) that paved the way for further progress. Combining legislative work with undercover farm and slaughterhouse investigations, litigation and corporate engagement, the HSUS and fellow animal protection organizations have made substantial progress in transitioning the ...
