Hub location-allocation in intermodal logistic networks

- Rafay Ishfaq, C. R. Sox
- Computer Science, Mathematics
- Eur. J. Oper. Res.
- 16 April 2011

Within the context of intermodal logistics, the design of transportation networks becomes more complex than it is for single mode logistics. In an intermodal network, the respective modes are… Expand

The capacitated lot sizing problem with setup carry-over

Although there is a significant amount of literature on the capacitated lot sizing problem, there has been insufficient consideration of planning problems in which it is possible for a lot size, or… Expand

Dynamic lot sizing with random demand and non-stationary costs

- C. R. Sox
- Mathematics, Computer Science
- Oper. Res. Lett.
- 1 May 1997

We describe a formulation of the dynamic lot sizing problem when demand is random and the costs are non-stationary. Assuming that the distribution of the cumulative demand is known for each period… Expand

Adaptive Inventory Control for Nonstationary Demand and Partial Information

- James T. Treharne, C. R. Sox
- Economics, Computer Science
- Manag. Sci.
- 1 May 2002

This paper examines several different policies for an inventory control problem in which the demand process is nonstationary and partially observed. The probability distribution for the demand in… Expand

A review of the stochastic lot scheduling problem 1 This paper is based upon work supported in part

- C. R. Sox, P. Jackson, A. Bowman, J. Muckstadt
- Economics
- 20 September 1999

Abstract This paper surveys the current research literature on the stochastic lot scheduling problem which deals with scheduling production of multiple products with random demand on a single… Expand

Design of intermodal logistics networks with hub delays

- Rafay Ishfaq, C. R. Sox
- Mathematics, Computer Science
- Eur. J. Oper. Res.
- 1 August 2012

In an intermodal hub network, cost benefits can be achieved through the use of intermodal shipments and the economies of scale due to consolidation of flows at the hubs. However, due to limited… Expand

Intermodal logistics: The interplay of financial, operational and service issues

- Rafay Ishfaq, C. R. Sox
- Economics
- 1 November 2010

This research addresses strategic planning for an interregional, hub based, intermodal logistics network operated by a logistics service provider. A tabu search meta-heuristic is used to solve a… Expand

“On-the-fly” line balancing with very little WIP

- J. McClain, L. Thomas, C. R. Sox
- Economics
- 1 October 1992

Abstract Dynamic line balancing (DLB) allows the workers on a production line to help each other with some tasks. However, for buffer capacity of 2 or less per stage, the advantage of DLB appeared to… Expand

Coordinating production and inventory to improve service

- C. R. Sox, L. Thomas, J. McClain
- Economics
- 1 September 1997

Customer service has assumed strategic importance in most manufacturing environments. Corporate reputations often depend on how reliably promised lead times are met. A goal of filling orders within a… Expand

Optimization-based planning for the stochastic lot-scheduling problem

- C. R. Sox, J. Muckstadt
- Mathematics
- 1 May 1997

We describe a finite-horizon stochastic optimization model for the stochastic lot-scheduling problem and procedures for finding near-optimal solutions. Several different products are produced by a… Expand
