In modern manufacturing systems like multi-resource constrained project scheduling problem with the multiple modes (mcPSP-mM) is complicated because of the complex interrelationships between the units of the different stages. In this paper, we develop an adaptive genetic algorithm (aGA) to solve the mcPSP-mM which is a well known NP-hard problem. A new aGA algorithm approach for solving these m...

A new hybrid flow shop scheduling problem with blocking is studied. The problem is characterized by multistage unrelated parallel machines and no intermediate buffer. Firstly, the math model of the hybrid scheduling problem is constructed. And then the computation method of production period is given. Due to there is no intermediate buffer, and there are unrelated parallel machines in multi-sta...

Abstract: In this paper, a method for determination of refractive index in membrane of fuel cell on basis of three-longitudinal-mode laser heterodyne interferometer is presented. The optical path difference between the target and reference paths is fixed and phase shift is then calculated in terms of refractive index shift. The measurement accuracy of this system is limited by nonlinearity erro...
