In this paper, the main problem and countermeasure of fruit production quality and safety were studied in Yanshan Mountain. The subjective factor was fruit farmer quality and safety consciousness faint, and the objective factors were: severe orchard environmental pollution, faint fruit postharvest handling, lag in process technology, fruit quality determination and market inspection system is n...

the map and the model designed by a designer and presented to a manufacturer in the form of a map is the result of his knowledge and innovation. the manufacturer, in turn, uses his best effort to produce a part accordingly. however, because of production problems and raw material, producing a precise part is very difficult and costly. one of the most important problems in this regard is designi...

The bubble effectiveness in liquid phase cylohexane non-catalytic oxidation process is discussed in this paper. Then the bubble effectiveness and a new proposed kinetic model are used in the mathematical model of the industrial reactor for the cyclohexane non-catalytic oxidation process. Furthermore, simulation and optimization based on this reactor model are carried out. The results of sim...

Injection Molding is a crucial segment of the plastics industry mainly due to its ability and flexibility to manufacture intricate components at high production rates and also with easy process flow. Injection molding has laid its hands over right from small parts to big machine parts. Plastic side release buckles, commonly employed in standard bags, suitcases and pouches, and are manufactured ...

This chapter deals with a mathematical model which gives an optimal production schedule in demand declining market if production system is imperfect (i.e. at any random time during production period machine shifts from 'in – control' state in to 'out – of control' state). This is a study about economic production in an imperfect production system. The imperfect production system means, a system...

We consider a make-to-stock supplier who operates a production facility with limited capacity. The supplier receives orders from customers belonging to several demand classes. Some of the customer classes share advance demand information with the supplier by announcing their orders ahead of their due date. However, this advance demand information is not perfect because the customer may decide t...

The Economic Production Quantity (EPQ) model is often used in the manufacturing sector to assist firms in determining the optimal production lot size that minimizes overall production-inventory costs. There are some assumptions in the EPQ model that restrict this model for real-world applications. Some of these assumptions are (1) infinite space of warehouse, (2) all of the pr...
