Although lot streaming scheduling is an active research field, lot streaming flexible flow lines problems have received far less attention than classical flow shops. This paper deals with scheduling jobs in lot streaming flexible flow line problems. The paper mathematically formulates the problem by a mixed integer linear programming model. This model solves small instances to optimality. Moreo...

In this paper, a Job shop scheduling problem with a parallel assembly stage and Lot Streaming (LS) is considered for the first time in both machining and assembly stages. Lot Streaming technique is a process of splitting jobs into smaller sub-jobs such that successive operations can be overlapped. Hence, to solve job shop scheduling problem with a parallel assembly stage and lot streaming, deci...

This paper addressed a Flexible Job shop Scheduling Problem (FJSP) with the objective of minimization of maximum completion time (Cmax) which job splitting or lot streaming is allowed. Lot streaming is an important technique that has been used widely to reduce completion time of a production system. Due to the complexity of the problem; exact optimization techniques such as branch and bound alg...

The multi-product variable lot streaming (MPVLS) in a flow shop is to determine product sequence, to determine the machines to reallocate lot streaming for each product in the sequence, and to determine lot streaming for each machine, in order to minimize makespan for producing all products. In this paper, MPVLS is decomposed into three sub-problems: product sequence determination, lot streamin...

We study lot streaming in shops in which the order the jobs are to be processed is immaterial. For a single job case, the properties of the optimal routing is determined. For the multi job case, two machine shops are analyzed. It is shown that lot streaming will improve makespan only if there is a job with large processing times. We show that there can be at most one such job and derive the opt...

Lot streaming is the process of splitting a production lot into sublots, and then scheduling the sublots in overlapping fashion on the machines, in order to improve the overall performance of the production system. Simulation-based and industry-based reports have con"rmed that substantial bene"ts are possible via lot streaming. In this paper, we present, for the "rst time, analytical results pe...
