With the purpose of minimizing the makespan of three-machine job shop scheduling problem with intermediate transfer, in this study, a new model was built to perform the makespan minimization, which was proved to be strongly NP-hard. From this model a heuristic algorithm was subsequently derived with a worst-case error bound. The proposed model and derived algorithm were verified through computational experiments carried out on a couple of small size random instances. The results show that the heuristic algorithm possesses a tight worst-case bound of 2. This research presents an approach for obtaining the optimal solutions of the NP-hard problem within a reasonable time.

“…Humidity is very important to human health, and living environment, such as relative humidity indoors being too high or too low and thus having an adverse effect on our living conditions [1][2][3][4]. Additionally, an excessively high or low relative humidity (RH) of the indoor air can cause various problems in the lives of people, such as the comfort of the occupants, the storage of goods, the durability of the outer structure of the building and energy consumption [5][6][7][8][9][10].…”

The hygrothermal performances of three types of zeolite-based humidity control building materials (ZBHCMs) were experimentally studied. The distributions of the pores and matrix of the ZBHCMs were visually characterized by micrographs. The saturated solution method was applied to measure the humidity control performance of the ZBHCMs. The effects of porosity, ambient temperature and relative humidity (RH) on the humidity control performance of the ZBHCMs were studied. The experimental results indicated that the humidity control performance of ZBHCMs is strongly affected by the porosity and the pore diameter. The environmental temperature and the RH have considerable influence on the adsorption performance of ZBHCMs. The desorption performance of ZBHCMs is affected more strongly by the ambient RH.

An accurate simulation on the hydrodynamic force of shallow lakes plays an important role on migration and transformation of lake pollutants and the change rules of lake pollution concentration as well. Based on a twodimensional unstructured shallow-water hydrodynamic model, the paper conducted numerical simulation research on the flow field of Wuxing Lake, and studied profoundly the impact of different wind fields, lake boundaries, inflow & outflow, and means of inflow & outflow on the flow field of Wuxing Lake. The results showed that: wind speeds tremendously influence circulation strength of Wuxing Lake, but don't work on circulation patterns; there appear transitive circulation patterns under southeast and northwest steady wind, but the two circulations in this pattern have opposite directions; on contrary, one great and strong circulation appears under the rest directions of wind; the influence of lake boundaries on the change of Wuxing Lake's flow speeds and flow directions is only significant in where the boundaries change, but slight in lake areas that are far away from where boundaries change; inflow & outflow are only effective in changing water flows in the lake inlet and lake outlet; the difference of inflow means and outflow means exerts certain influence on flow fields in Wuxing Lake, but among them, the fluctuation means help improve the aquatic environment in Wuxing Lake. The research in the paper provides fundamental scientific bases for reconstructing a healthy ecological system of Wuxing Lake.
