A continuous production control inventory model for deteriorating items with variable demand rate is developed. Demand rate is the linear function of time. In this paper we have done all work in the environment of permissible delay of payments. A number of structural properties of the inventory system are studied analytically. We have discussed the minimum total system cost under the condition ...

About two-thirds of the contracts are of long duration of three years, and the remaining are of two years or eleven months duration.

Ödemede belirli bir süre gecikmeye izin verilmesi varsayımının toplam maliyet üzerindeki etkisi birçok üretim stok kontrol modelinde ele alınmıştır. Bu modellerde, ödemede verilen gecikme süresinin alıcının satın alma kararını etkilediği bu durumun da maliyetlerini önemli ölçüde azalttığı sonucuna varılmıştır. Stok azaltmanın diğer yolu sırasında üretilen kusurlu ürünlerin tamir edilmesidir. ça...

We explore this fundamental question using granular project-level and firm-level data from the pharmaceutical industry, focusing on particular mechanism through which incumbent firms maintain their power: “reverse payment” or “pay-for-delay” agreements delay entry of competitors. first show that when are unfe...
