This paper discusses the makespan minimization of a production batch within a specific concurrent system, seru production system. A seru production system consists of multiple independent serus. A seru is a compact assembly origination in which products are assembled...

Today's volatile market conditions in electronic industries have lead to a new production system, seru (which is the Japanese pronunciation for cell), and has been widely implemented in hundreds of Japanese and other Asia companies. In particular, the rotating seru has been widely implemented,...

As a fundamental logistics service, the express delivery (ED) industry provides production and consumption activities to maintain efficient supply chain operations. It plays an important role in promoting industrial development and maintaining daily life and consumption. This study examined the...

Mitigating the adverse effects of uncertainty in appointment systems, arising from heterogeneous patient needs and preferences, is critical to the effective use of scarce medical resources and patient satisfaction. This study addresses an online scheduling problem with multiple servers and...

This paper investigates the production scheduling problems of allocating resources and sequencing jobs in the seru production system (SPS). As a new-type manufacturing mode arising from Japanese production practices, seru production can achieve efficiency, flexibility, and responsiveness...

The problem of designing a rebalancing algorithm for a large-scale ridehailing system with asymmetric (unbalanced) demand is considered here. We pose the rebalancing problem within a semi Markov decision problem (SMDP) framework with closed queues of vehicles serving stationary, but asymmetric...
