this study is concerned with encouraging people to use post system in iran. in fact, it tries to find the design specifications of a post machine as an interacting system for improving post system. a machine that can provide facilities for posting parcels and selling envelops and stamps. in iran, post system is an obsolete system and cannot satisfy the users completely. in order to explore the ...

regarding the importance sizing and grading crop in the market and other processing operations, in this study, a machine for hazelnut sizing designed, constructed and evaluated. the machine based on sizing mechanism of diverged belt. the sizing unit has a structure similar to a horizontal belt conveyor. the distance between the ropes at the entrance of the product (the end of the driven roller)...

this paper focuses on multi-objective designing of multi-machine thyristor controlled series compensator (tcsc) using strength pareto evolutionary algorithm (spea). the tcsc parameters designing problem is converted to an optimization problem with the multi-objective function including the desired damping factor and the desired damping ratio of the power system modes, which is solved by a spea ...

equipment availability is necessary in the development of agriculture mechanization. crop thinning is one of the most important stages in row crop production which is laborious and costly. the objective of this project is design and construction of a row crop thinning machine. four main system units are plant sensors, ground sensors, control and thinning platforms. in this machine the unwanted ...

Clustering parts and machines into part families and machine cells is a major decision in the design of cellular manufacturing systems which is defined as cell formation. This paper presents a non-linear mixed integer programming model to design cellular manufacturing systems which assumes that the arrival rate of parts into cells and machine service rate are stochastic parameters and descri...

dynamic cellular manufacturing systems,   mixed-integer non-linear programming,   production planning, manufacturing attributes   this paper presents a novel mixed-integer non-linear programming model for the design of a dynamic cellular manufacturing system (dcms) based on production planning (pp) decisions and several manufacturing attributes. such an integrated dcms model with an extensive c...
