In this paper, no-wait job shop problems with makespan minimization are considered. It is well known that these problems are strongly NP-hard. The problem is decomposed into the sequencing and the timetabling components. Shift timetabling is developed for the timetabling component. An effective...

According to spatial distribution of climate disasters in Nanning City and physiological and ecological indicator demands of sugarcane, with the aid of HJ-1 CCD satellite remote sensing images, basic meteorological data and geographic information data, this paper established the model for...

For the no-wait flowshop scheduling problem with maximum lateness criterion, properties are developed to speed up three kinds of basic operations generating candidate solutions, i.e., the insertion of a new job into a partial sequence, and the insertion and exchange neighborhood moves. The...

In this paper, a HGA (hybrid genetic algorithm) is proposed for permutation flowshop scheduling problems (PFSP) with total flowtime minimization, which are known to be NP-hard. One of the chromosomes in the initial population is constructed by a suitable heuristic and the others are yielded...

In this paper, permutation flow shops with total flowtime minimization are considered. General flowtime computing (GFC) is presented to accelerate flowtime computation. A newly generated schedule is divided into an unchanged subsequence and a changed part. GFC computes total flowtime of a...

We build a Markov regime switching model to examine the role of heterogeneous expectations in the forward exchange market, where the regime could be fundamentalists or chartists. Our empirical analysis of EUR/USD and USD/JPY forward markets suggest that the fundamen-talists who follow negative...

The primary goal of this study was to investigate the mediator effects of loneliness and subjective happiness on the relationship between core self-evaluations and life satisfaction in Chinese college students. A total of 301 participants were all students who were attending three different...

Conservation tillage and fertilization based on soil test have been promoted by the Chinese government in recent years. Their impacts on non-point source pollution were simulated using the Soil and Water Assessment Tool (SWAT) for the Liuxi River watershed, the only one local...

Increasing calls for a social security reform of switching from the pay-as-you-go (PAYG) system to a funded system has been seen in recent decades. This paper examines the effect of this reform on capital accumulation and the welfare of each generation. Three methods are used to finance the...

Since the founding of the People's Republic, Jiangsu's public finance has taken its stand on reform and served society. It has attained heartening progress.
