This paper deals with the single machine multi-product lot scheduling problem in which defective items are produced in any production run of each product. We have adopted the common cycle scheduling policy and assumed that the setup times for production of each product can be non-zero. Further, we have assumed that defective items will be reworked and the inspection costs during the normal prod...

previous electronic commerce (ec) studies have found thatconsumer characteristics are important when considering issues related tothe acceptance of online shopping. however, most studies have focusedon a single product or similar products. the effects of different producttypes have been relatively neglected. to overcome this limitation, thepurpose of this study was to explore the effects of dif...

Analytic approximations of the time-evolution of the single enzyme-substrate reaction are valid for all but a small region of parameter spsce in the positive initial enzyme-initial substrate concentration plane. We find velocity equations for the substrate decomposition and product formation with the aid of the total quasi-steady-state approximation and an aggregation technique for cases where ...
