چکیده
This paper presents a model for optimizing both software and hardware reliability for embedded systems under cost and multiple reliability constraints. Previously, most optimization models have been developed for hardware-only or software-only systems by assuming the hardware, if any, has perfect reliability. In addition they assume that failures for each hardware or software component is statistically independent. In other words, none of the existing optimization models was developed for hardware & software (called embedded) systems with failure dependencies. Our model minimizes system cost under multiple reliability constraints. We use our model for an embedded system with multiple applications sharing multiple resources. This is the first time that optimization of this kind of model is performed on this type of system.

متن کاملCost Models for Electronic Architecture Trade Studies
This paper presents a model for estimating the total cost of a proposed electronic architecture for embedded, distributed, real-time systems. The main purpose of the model is to allow system engineers to compare different solution alternatives with respect to cost, in order to perform an early optimization. This is necessary to cope with the complexity of such systems, and make them profitable ...

This article develops an integrated JIT lot-splitting model for a single supplier and a single buyer. In this model we consider reduction of setup time, and the optimal lot size are obtained due to reduced setup time in the context of joint optimization for both buyer and supplier, under deterministic condition with a single product. Two cases are discussed: Single Delivery (SD) case, and Multi...
