In this paper we present a unified (probabilistic/possibilistic) model for resource-constrained project scheduling problem (RCPSP) with uncertain activity durations and a concept of a heuristic approach connected to the theoretical model. It is shown that the uncertainty management can be built into any heuristic algorithm developed to solve RCPSP with deterministic activity durations. The esse...

Offshore engineering construction projects are large and complex, having the characteristics of multiple execution modes resource constraints. Their complex internal scheduling processes can be regarded as resourceconstrained project problems (RCPSPs). To solve RCPSP in offshore more rapidly, a hybrid genetic algorithm was established. defects algorithms, which easily fall into local optimal so...

The emergence of heterogeneous applications with diverse requirements for resource-constrained Wireless Body Area Networks (WBANs) poses significant challenges for provisioning Quality of Service (QoS) with multi-constraints (delay and reliability) while preserving energy efficiency. To address such challenges, this paper proposes McMAC,a MAC protocol with multi-constrained QoS provisioning for...

Device-to-Device (D2D) paradigm is one of the key enablers for boosting energy efficiency (EE) networks. For actualization EE in multi-mode heterogeneous D2D networks, resource allocation should be executed accordingly. In that regard, we study management networks where there a LEO satellite and cellular base station (BS) with user devices (satellite, BS connectivity modes) dispersed terrestria...
