Estimating manufacturing costs of a new product or process soon after research and development (R&D) has commenced can provide a good indication of the project’s economic viability. “Early” estimates can be used to direct research efforts to promising opportunities for cost reduction, and allow businesses to better assign resources to new products. Although potentially compromised because some ...

Suppose that infinitesimal firms have identical variable costs but there is heterogeneity in their fixed costs. Regardless of the ordering of entry and exit, fixed costs will be minimized for a given industry size. Journal of Economic Literature Classifications: L11 & L13

This paper formulates a mathematical model for the Green Vehicle Routing Problem (GVRP), incorporating bi-fuel (natural gas and gasoline) pickup trucks in a mixed vehicle fleet. The objective is to minimize overall costs relating to service (earliness and tardiness), transportation (fixed, variable and fuel), and carbon emissions. To reflect a real-world situation, the study considers: (1) a co...

background and aims: burn injuries gives rise to mortality and long-term disability, and impose a high economic burden on patients, their families, and society.  thus, we investigated the direct hospitalization costs of the 388 burn patients admitted to the burn center of imam khomeini hospital in kermanshah province of iran. material and methods: this  retrospective study was conducted on all ...

We consider a model for a serial supply chain in which production, inventory, and transportation decisions are integrated, in the presence of production capacities and for different transportation cost functions. The model we study is a generalization of the traditional single-item economic lot-sizing model, adding stationary production capacities at the manufacturer, as well as multiple interm...

Results and costs of the first six months experience with BACTEC NR-730 were compared with a series of blood cultures performed by the conventional method previously used. The newer technology detected the growth of 14.1% of significant isolates on the day of receipt of the specimens. The previous method lacked blind subcultures on the day of receipt and therefore detected growth only after ove...

T transfer to low-cost locations offers global firms an opportunity to reduce their variable costs involved in serving emerging markets. However, such moves may also make imitation by local competitors easier. As a consequence, technology transfer may create competition in the local market. We introduce component-based technology transfer for the global firm as a means to deter or accommodate t...
