We study the operations scheduling problem with delivery deadlines in a three-stage supply chain process consisting of (1) heterogeneous suppliers, (2) capacitated processing centres (PCs), and (3) a network of business customers. The suppliers make and ship semi-finished products to the PCs...

This paper focuses on single machine scheduling subject to inventory constraints. Jobs either add items to an inventory or remove items from that inventory. Jobs that have to remove items cannot be processed if the required number of items is not available. We consider scheduling problems on a...

We consider semi-online scheduling problems on parallel machines to minimize the makespan subject to Grade of Service (GoS) eligibility constraints with different prior information: (1) the known total processing time, (2) the known largest processing time, (3) the known both total and largest...

We consider parallel machine scheduling problems where the processing of the jobs on the machines involves two types of objectives. The first type is one of two classical objective functions in scheduling theory: either the total completion time or the makespan. The second type involves an...

We consider coordination mechanisms for the distributed scheduling of n jobs on m parallel machines, where each agent holding a job selects a machine to process his/her own job. Without a central authority to construct a schedule, each agent acts selfishly to minimize his/her own disutility,...

This paper considers a two-stage production scheduling problem in which each activity requires two operations to be processed in stages 1 and 2, respectively. There are two options for processing each operation: the first is to produce it by utilizing in-house resources, while the second is to...

We consider the m-machine ordered flow shop scheduling problem with machines subject to maintenance and with the makespan as objective. It is assumed that the maintenances are scheduled in advance and that the jobs are resumable. We consider permutation schedules and show that the problem is...

International markets for agricultural products are often subject to a range of trade barriers, and horticultural products are no exception. This paper examines the economic implications of tariffs and sanitary and phytosanitary (SPS) regulations that are applied to global markets for fresh...

This study explores how both gender and facial attractiveness affect job candidates' chances of obtaining interviews in China's dynamic Internet job board labor market. It examines how discrimination based on these attributes varies over occupation, location, and firms' ownership type and size....

To enhance Chinese agricultural production, improve food quality, build consumer trust, and encourage the export of agricultural products, the Chinese government designed the Chinese version of Good Agricultural Practice (ChinaGAP) based on the main principles of the GlobalGAP combining the...
