Abstract: Most of the inventory models assume perfect production, but it is not necessary that all the units produced in manufacturing organisation are of excellent quality. This can be a mix of perfect and imperfect quality. This type of production is in the category of imperfect production process. In this article, we create a production model for ameliorating inventory system with time-varying demand. Here, the term 'amelioration' refers to improvement in the goods which causes value increase or benefit from the amount used at the time. The production cost per unit is considered as a function of the production rate. Mathematical expression for the expected profit is calculated and a numerical example is given to illustrate the model. Also, the effects of parameters involved in the modelling are examined with the help of sensitivity analysis.

Keywords: inventory modelling; perfect quality items; imperfect quality items; variable production cost; amelioration; time varying demand; manufacturing industry; quality improvement. (search for similar items in EconPapers)
