In this paper, we consider a variant of the classical parallel machine scheduling problem. For this problem, we are given m potential identical machines to non-preemptively process a sequence of independent jobs. Machines need to be activated before starting to process, and each machine...

We study a preemptive scheduling problem on two identical parallel machines that share a common server. Each job has to be loaded by the server before being processed on one of the machines and unloaded by the server after its processing. The loading and unloading times are both equal to one...

In this paper, we investigate the capacitated two-parallel machines scheduling problem, where one machine is only available for a special period of time after which it can no longer process any job while the other machine is continuously available. Our objective is to minimize the completion...

Given a network N(V, A, u, c) and a feasible flow x0, an inverse minimum cost flow problem is to modify the cost vector as little as possible to make x0 form a minimum cost flow of the network. The modification can be measured by different norms. In this paper, we consider the inverse minimum...

We estimate the evolution of healthcare demand under the influence of income growth and population aging with two samples of patients surveyed in the same regions, but with an interval of 18 years in rural China and with mixed logit to deal with heterogeneity. In accordance with theoretical and...

In order to analyze the electric-power demand and supply in China efficiently, this paper presents a Grey–Markov forecasting model to forecast the electric-power demand in China. This method takes into account the general trend series and random fluctuations about original time-series data. It...

One of the most important aspects of metal mine design is to determine the optimum cut-off grades and milling grades which relate to the economic efficiency of enterprises and the service life of mines. This paper proposes a hybrid intelligent framework which is based on stochastic simulations...

This study aims at testing the theoretical issue according to which multinomial logit (MNL) would give lower performance than a mixed multinomial logit (MMNL) in the presence of heterogeneity. To do so, we construct two samples of patients surveyed within the same regions in rural China, but of...

The main purpose of this paper is to study the ordering, transshipment price, wholesale price and contracting decisions of a dual-channel supply chain with unidirectional transshipment. We establish a dual-channel model which consists of a manufacturer, an online shop owned by a manufacturer and...

This paper uses Comtrade panel data to assess the impacts of imports from China, in comparison with those from the United States and France, on Sub-Saharan African manufactured exports (as proxies of production performance). It is found that Chinese impacts are significantly positive in all...
