We proposed the flexible thermoelectric generator (TEG) using double side FPCB (flexible printed circuit boards). The proposed flexible thermoelectric generator has the unique vertical structure. The heat of the flexible thermoelectric generator flows vertically via plated through hole (PTH). The n-type (Bi-Te) and p-type (Sb-Te) thin films are deposited by the co-evaporator and patterned using...

in this paper, we considered solving approaches to flexible job shop problems. makespan is not a good evaluation criterion with overlapping in operations assumption. accordingly, in addition to makespan, we used total machine work loading time and critical machine work loading time as evaluation criteria. as overlapping in operations is a practical assumption in chemical, petrochemical, and gla...

This paper considers our work in progress on the problem of scheduling production activities in a real-life manufacturing plant. The problem is modelled as a two-stage flexible flow shop problem with minimization of the makespan and the number of tardy jobs. The design approach of an evolutionary algorithm is described. Preliminary experiments are performed and results obtained show the improve...

The Distributed and Flexible Job-shop Scheduling problem (DFJS) considers the scheduling of distributed manufacturing environments, where jobs are processed by a system of several Flexible Manufacturing Units (FMUs). Distributed scheduling problems deal with the assignment of jobs to FMUs and with determining the scheduling of each FMU, in terms of assignment of each job operation to one of the...

In mass customization (MC), the assembly operations of modular products tend to be organized as form flexible mixed-model line (FMMAL). The dynamic scheduling problem FMMAL is quite complex with product sequencing, station allocation, material delivery, disruption events failure, inserting and reworking. To solve these problems, a comprehensive framework combining architecture Internet Manufact...

In this paper we utilize extrinsic information transfer (EXIT) chart analysis in a coded direct-sequence codedivision multiple-access (DS-CDMA) multiuser receiver to dynamically derive the optimal decoding schedule in the unequal user power level case. Conventional receivers generally follow a predetermined decoding schedule. However, decoding delay and complexity can be significantly reduced w...

Scheduling, resource allocation and binding are traditionally classified as behavioral synthesis tasks. However, advanced RTL synthesis tools could execute the last two tasks. Hence, an overlap of functionality will be found in most new design environments. In this paper, we present a new design flow with flexible frontiers between behavioral and RTL synthesis tools. Our results show that it is...

The present paper is an attempt to develop a new heuristic algorithm, find the optimal sequence to minimize the utilization time of the machines and hence their rental cost for two stage specially structured flow shop scheduling under specified rental policy in which processing times and set up time are associated with their respective probabilities including transportation time. Further jo...

This paper considers an on-line scheduling problem occurred in a service system with two classes (ordinary and special) of customers and two types (dedicated and flexible) of servers. The customers line up with a list according to the order of their arrivals. All customers are assumed to be in the system when service starts and no preemption is allowed. The objective is to complete all services...
