Sheet metal bending press-brakes can be setup to produce more than one type of part without requiring a setup change. To exploit this flexibility, we need setup planning techniques so that press-brake setups can be shared among many different parts. In this paper, we describe algorithms for partitioning a given set of parts into setup compatible part families that can be produced on the same se...

The main purpose of this study is to investigate the periodic inventory model with backorder price discounts, where shortages are partially backlogged. The application of just-in-time (JIT) philosophy i.e., crashing of the lead-time and setup cost has been carried component wise. Two cases have been discussed viz 1 protection interval demand distribution is known (normal distribution approach) ...

In IP Multimedia Subsystem (IMS), the session setup delay is a critical value for Quality of Service (QoS). The existing approaches to improve this metric depend on optimization of Session Initiation Protocol (SIP) message transmitting and signaling flows. Unfortunately, some service features are missing considered although they have been used widely in traditional 2G networks. This paper propo...

This paper proposes a production-inventory model with setup cost for production and financial compensation for stopping production when the buy-back program is activated, which is a modified model to that of [Chen et al 2007] by including the setup cost. Under an energy buyback program, we consider M+1 types of market scenarios and the corresponding buy-back levels with different financial comp...
