This paper addresses minimizing Total Weighted Earliness/Tardiness (TWET) of jobs in a Flexible Job Shop (FJS) problem. The FJS problem is an extension of the classical Job Shop (JS) problem that implies each operation may be assigned to alternative available machines. So, a job may have alternative routing. The FJS problem with a TWET criterion is modeled as a mixed integer programming. The mo...
Today’s company competiveness is favoured by product customisation and fast delivery. A strategy to meet this challenge is to manufacture standard items to stock for product customisation. This configures a hybrid environment of make-to-stock and make-to-order. To explore the advantages of this requires good understanding of production control. Thus, we study production under hybrid MTS-MTO, or...
In single machine scheduling problems with availability constraints, machines are not available for one or more periods of time. In this paper, we consider a single machine scheduling problem with flexible and periodic availability constraints. In this problem, the maximum continuous working time for each machine increases in a stepwise manner with two different values allowed. Also, the durati...
This paper considers the scheduling of n jobs on m parallel machines to minimize the weighted number of early and tardy jobs. The single machine case of this problem has been shown to be NPcomplete in the strong sense. This problem on m parallel machine is also NP complete in the strong sense and finding an optimal solution appears unlikely. The problem is formulated as an integer linear progra...
BACKGROUND Job satisfaction among health workers is an important indicator in assessing the performance and efficiency of health services. OBJECTIVE This study measured job satisfaction and determined associated factors among health workers in 38 commune health stations in an urban district and a rural district of Hanoi, Vietnam. A total of 252 health workers (36 medical doctors and 216 nurse...
Abstract Meeting customer time requirements poses a major challenge in the context of high‐variety make‐to‐order companies. Companies need to reduce lead and process urgent jobs time, while realising high delivery reliability. The key decision stages within Workload Control (WLC) are order release shop floor dispatching. To best our knowledge, recent research has mainly focused on stage inadver...
aims: job rotation is considered as one of the human resource development methods. this study was carried out to investigate the correlation between job rotation and visiting number of environmental health employees. materials & methods: this descriptive cross-sectional study was done on environmental health employees in three health centers of north, north west and east of tehran in 2011. 42 p...
