In his 1996 work developing the theory of association schemes as a ‘generalized’ group theory, Zieschang introduced the concept of the semidirect product as a possible product operation of certain association schemes. In this paper we extend the semidirect product operation into the entire set of association schemes. We then derive a way to decompose certain association schemes into smaller ass...

This paper examines the process of operative planning production an industrial company under conditions random fluctuations in current demand. It is shown that these there are losses, size which depends on adopted policy operation activity. The activity understood as rule making decisions volumes based information about incoming orders, probable future demand, and possible losses due to deviati...

We study the cross product as a method for generating and analyzing interconnection network topologies for multiprocessor systems. Consider two interconnection graphs G1 and G2 each with some established properties such as symmetry, low degree and diameter, scalability, simple optimal routing, recursive structure (partitionability), fault tolerance, existence of nodedisjoint paths, low cost emb...

in this study the efficacy of intermittent and continuous drying processes on fissuring of hashemi and koohsar varieties was investigated. the fissuring of the kernels was assessed based on stress cracking index (sci). the experiments were carried out at drying and tempering temperatures of 30, 45 and 60 °c, drying durations of 20, 40 and 60 min, and constant tempering duration of 80 min. in co...

Exergy analysis is based on combined first and second laws of thermodynamics and is a useful tool to analyze the energy systems in a better and more realistic way than an energy analysis, based on the first law of thermodynamics. Combination of exergy from thermodynamics with conventional concepts from engineering economy which is referred to as thermo-economy (exergo-economy) is a valuable too...

Elaborating an appropriate cellular manufacturing system (CMS) could solve many structural and operational issues. Thereby, considering some significant factors as worker skill, machine hardness, and product quality levels could assist the companies in current competitive environment. This paper proposes a novel interactive possibilistic mixed integer nonlinear approach to minimize the total co...
