The article presents information on various articles published in the 1995 issue of the journal "Transportation Science." One of the articles was "The Economic Lot and Delivery Scheduling Problem." It discusses the coordination of production and outbound delivery schedules has become more important with the adoption of "just-in-time" policies. Many "just-in-time" suppliers feel that they are being forced to hold inventory for their customers, which raises two important questions. First, to find out what characterizes a good production and delivery schedules under the existing economics of transportation and production. Second, is to understand when suppliers hold inventory. Another article in the periodical was "Markovian Decision Processes in Shipment Consolidation." Deciding when a manufacturer or distributor should dispatch a vehicle carrying orders to many customers affects both the cost and service of the shipment consolidation program. Shipping too early results in load sizes that may be too small to achieve transportation economies, while large loads imply long waiting times. Many approaches to this decision a target quantity based on average performances and continue to accumulate orders until this target is reached.

    When making lot-sizing decisions, managers often use a model horizon T that is much smaller than any reasonable estimate of the firm's future horizons. This is done because forecast accuracy deteriorates rapidly for longer horizons, while computational burden increases. However, what is optimal...

    Many practical applications of lot-sizing and scheduling problems involve start-up times. Operations research literature contains but few studies of lot-sizing models that take start-up times explicitly into account. Here, we review some of these studies, discuss the models and their complexity,...

    Machine sequencing formulations typically assume that the characteristics of the job set to be processed are given. However, in many applications, jobs can be hatched in different ways. Two types of minimum flow-time sequencing problems with lot sizing are formulated. The "itemflow" formulation...

It is known that the optimal type of control policy is a control limit policy: service should begin if and only if the number of waiting customers is at...
