Using the three-field notation of Graham et al. (1979) for scheduling problems, we denote the flow shop problem with unlimited intermediate buffers and two distinct due dates as the Fm|dj∈d1,d2|Lmax problem and the no-wait flow shop problem with two distinct due dates as the Fm|nwt,...
After a brief literature review on flow-shop and job-shop scheduling, we provide a mathematical formulation and analyze the complexity of the problem. Then, we determine various particular cases that can be solved by known methods, and we identify dominance rules for this problem. After setting ...
Automated guided vehicles have been widely used in flexible manufacturing systems especially in a job shop and flow shop. Recently, they are included in other fields such as container terminals. This paper demonstrates a literature review of the last three decades about the scheduling problems of th...

Flexible job shop scheduling combined strategy According to the above analysis, the model is transformed into a distinct scheduling scheme based on the triangular fuzzy number model, and the rescheduling methods corresponding to tardiness disturbance is proposed. 3.1 Operation flow. Firstly, according to...
Flow shop non-idle scheduling and resource-constrained scheduling Article 27 November 2015 Notes The motivation for this is twofold: it has already proved fruitful to model the job shop problem in terms of AND/OR graphs (Hvalica and Bogataj 2005) and the same applies to modelling the ...
In a general flow-shop situation, where all the jobs must pass through all the machines in the same order, certain heuristic algorithms propose that the jobs with higher total process time should be given higher priority than the jobs with less total process time. Based on this premise, a ...
proposed a scheduling rule ranking method for a multi-objective dynamic flow shop scheduling system based on data envelopment analysis and a basic scheduling strategy that can switch between different preferred rules according to the average deadline closeness of the current work portfolio in the shop...
job shop, a CPS based on mobile edge computing (MEC) middleware is proposed. First, the CPS and MEC for a service-oriented production process are analyzed. Secondly, based on MEC middleware, a CPS architecture model of a smart job shop is established. Then, the implementation of MEC ...
My bottom line is to not pay more than $250 for the theme and add-ons. In addition to the job theme (TBA) AND wp job manager, should I get core bundle add-on pack (listed above) or just the 4 add-ons – resume manager, restrict content pro, indeed integration and apply with lin...
