The Development Assurance Level (DAL) indicates the level of rigor of the development of a software or hardware function of an aircraft. We propose a theory formalizing the DAL allocation rules found in the ARP4754a recommended practices. A tool implementing this theory was developed in order to assist the safety specialists when checking or optimizing a DAL allocation.

Firms with omni-channel multi-echelon distribution networks (OMDC) integrate all of their sale channels and echelons to achieve an effective matching multi-type orders a shared inventory. However, the high operational cost caused by insufficient use inventory resources unreasonable order allocation restricts sustainable development firms. To this end, joint decisions optimization (IO) (OA) are ...

The optimizations with respect to the supply chain management have far-reaching effects on enterprise development as well people’s livelihood. By this fact, it is important solve order allocation problem in a real scenario. We focus optimising marketing (SMOAP) various constraints from an algorithmic aspect. SMOAP considers how match orders between purchasers and suppliers maximise platform’s b...

We consider a supply chain in which a single supplier with fixed capacity sells to several independent retailers or manufacturers. The retailers have private information about their individual markets (e.g., mean market demand), which influences the size of their orders to the supplier. If the sum of all retailer orders exceeds the supplier’s capacity, the supplier uses a pre-declared rule, whi...

This paper proposes a new rate allocation method for MPEG-4 fine granularity scalable (FGS) video streaming, with which the received image quality can be smoothed during the streaming period. Although average bit rate allocation is quite simple, the image’s quality changes greatly between frames, which will result in quality fluctuation and degrade the streaming quality. In this paper the bits ...
