classical deterministic inventory models consider the demand rate to be either constant or time-dependent but independent from the stock status. however, for a certain type of inventory, the demand rate may be in-fluenced by the stock level. also in many real-life problems, some products such as fruits, vegetables, phar-maceuticals and volatile liquids continuously deteriorate to evaporation, o...

in this paper, the researchers present a multi-objective linear fractional inventory model using fuzzy pro-gramming. the proposed method in this paper is applied to a problem with two objective functions. the re-sulted fuzzy model is transformed into an ordinary linear programming. the implementation of the develop-ing model presented in this paper is demonstrated through the use of some numeri...

This paper studies a bandwidth-limited federated learning (FL) system where the access point is central server for aggregation and energy-constrained user equipemnts (UEs) with limited computation capabilities (e.g., Internet of Things devices) perform local training. Limited by bandwidth in wireless edge systems, only part UEs can participate each FL training round. Selecting different could a...

There are meta-object protocols (MOPs) that do not provide support for meta-object composition. Others require explicit modii-cation of existing meta-level code or provide a limited delegation mechanism in order to support it. There is much room for improvement in this eld. The MOP of Guaran a favors the development of meta-objects that can be easily composed. Composers are meta-objects that de...

This article investigates the security issues raised by the use of meta-programming systems with Java. For each possible type of MOP (compile-time, load-time, etc.), we study what are the permissions required for both the base and the meta-level protection domains, taking into account the ow of control between the di erent parts of the application. We show that the choice of a particular MOP ar...

Buprenorphine, a maintenance drug for heroin addicts, exerts its pharmacological function via κ- (KOP), μ-opioid (MOP) and nociceptin/opioid receptor-like 1 (NOP) receptors. Previously, we investigated its effects in an in vitro model expressing human MOP and NOP receptors individually or simultaneously (MOP, NOP, and MOP+NOP) in human embryonic kidney 293 cells. Here, we expanded this cell mod...

in this research, we address the application of uncertaintyprogramming to design a multi-site, multi-product, multi-period,closed-loop supply chain (clsc) network. in order to make theresults of this article more realistic, a clsc for a case study inthe iron and steel industry has been explored. the presentedsupply chain covers three objective functions: maximization ofprofit, minimization of n...

Optimizing the structure of land use is essential to low-carbon sustainable development a region. This article takes Chengdu, typical western China city, as case study. First, carbon emission coefficients are used calculate emissions. Then, based on multi-objective linear programming (MOP), economic priority scenario (S1), (S2), and strengthening (S3) proposed. Finally, future simulation (FLUS)...
