Based on free-electron model, the calculated inelastic mean escape depth of secondary electrons, experimental one, the energy band of metal, the characteristics and processes of secondary electron emission, maximum number of secondary electrons released per primary electron δ(Φ,EF)PEm as a...

Due to the increasing concerns about global warming, low-carbon production has been a hot topic around the world. In this paper, carbon emissions reduction and project makespan minimization are considered simultaneously. To formulate the problem, a multi-objective multi-mode resource-constrained...

A novel Discrete Differential Evolution (DDE) algorithm is proposed in this paper for solving no-idle permutation flow-shop scheduling problems with maximum completion time (makespan) criterion. Firstly, individuals of the DDE algorithm are represented as discrete job permutations, and new...

A new policy, referred to as the condition-based replacement and spare provisioning policy, is presented for deteriorating systems with a number of identical units. It combines the condition-based replacement policy with periodical inspections and the (S,s) type inventory policy, noted as the...

The blocking flowshop scheduling problem with makespan criterion has important applications in a variety of industrial systems. Heuristics that explore specific characteristics of the problem are essential for many practical systems to find good solutions with limited computational effort. This...

Using inter-jurisdictional differences in the implementation of the Family Allowance Program in Canada in the mid-1970s, this paper first shows that Quebec families with two or more children prior to being exposed to the program responded quite strongly to the added incentives in the short run...

In this paper, we consider a three-machine permutation flow shop scheduling problem under simple linear deterioration. By a simple linear deterioration function, we mean that the processing time of a job is a simple linear function of its execution start time. The objective is to find a sequence...

In this paper we compare the size distortions and powers for Pearson's [chi]2-statistic, likelihood ratio statistic LR, score statistic SC and two statistics, which we call UT and VT here, proposed by [Potthoff, R.F., Whittinghill, M., 1966. Testing for homogeneity: II. The Poisson distribution....
