this paper presents a mathematical model for a flow shop scheduling problem consisting of m machine and n jobs with fuzzy processing times that can be estimated as independent stochastic or fuzzy numbers. in the traditional flow shop scheduling problem, the typical objective is to minimize the makespan). however,, two significant criteria for each schedule in stochastic models are: expectable m...

This article reports on the discussion of linguistic landscape in course tourism peripheries. The central aim is to unravel salience and visibility language practices manifested shop-fronts Bali peripherals. Drawing Bourdieu’s as social power (1983; 1993), presentation-of-self (Goffman, 1963; 1981), good-reasons perspective (Boudon, 1990) we explore choices made by local shop owners principles ...

During last decades, developing multi-objective evolutionary algorithms for optimization problems has found considerable attention. Flexible job shop scheduling problem, as an important scheduling optimization problem, has found this attention too. However, most of the multi-objective algorithms that are developed for this problem use nonprofessional approaches. In another words, most of them c...

Permutation Flow Shop Scheduling Problem (PFSP) is a complex combinatorial optimization problem with strong engineering background. To solve the PFSP with makespan criterions, an immune particle swarm optimization (IPSO) algorithm was proposed. The initial solution of the algorithm is generated by the famous heuristic NEH algorithm, it was used to initialize the particle of global extreme value...

Proper scheduling of tasks leads to optimum using of time and resources, in order to obtaining best result. One of the most important and complicated scheduling problems is open shop scheduling problem. There are n jobs in open shop scheduling problem which should be processed by m machines. Purpose of scheduling open shop problem is attaining to a suitable order of processing jobs by specified...

in this paper, an exact geometric algorithm is presented for solving two-job sequencing and scheduling problems in flexible flow shop and job shop environments while the resources are (un)available in some time periods and processors (un)availability is the same in all work centers. this study seems utterly new and it is applicable to any performance measure based on the completion time. the in...

Sir,?In the course of my holiday rambles in the North, I have come across dirty cows being milked in the dirtiest possible surroundings. I cannot too strongly express my horror to think that milk, probably to be seen, a few hours later, in brightly burnished churns on white tiles in some spotless city dairy shop, is being produced under unspeakably filthy conditions. I need not go into details ...
