This study addresses the efficiency of multiple threads Tabu search (TS) in solving scheduling problems. Nowadays, most desktop personal computers equip with multicore CPU. It is possible to achieve parallel searching strategy on a desktop computer. A problem of scheduling, which minimizes the total tardiness of a set of jobs to be scheduled on parallel identical machines, is presented as an example in this study. The parallel program uses Open Multi-Processing (OpenMP) library under Microsoft Visual Studio 2010 environment. An experiment of different number of jobs is executed by the parallel Tabu search program with different number of threads, and the results of single thread and multithreads are discussed. In sum, the more threads used for searching process, the lager instances to get a better solution.
本文研究了多线程禁忌搜索(TS)在解决调度问题中的效率。如今，大多数台式个人电脑都配备了多核CPU。在台式计算机上实现并行搜索策略是可能的。本文以调度问题为例，讨论了在并行相同机器上调度的一组作业的总延迟最小化问题。并行程序使用Microsoft Visual Studio 2010环境下的OpenMP库。用不同线程数的并行禁忌搜索程序执行了不同任务数的实验，并讨论了单线程和多线程的结果。总而言之，用于搜索进程的线程越多，实例越多，得到的解决方案越好。

This paper considers that a company is planning to produce innovative products in an uncertain market environment. We build production planning models with the one-shot decision theory (OSDT) where the optimal production plan is obtained to correspond to some special scenarios. Since the OSDT based production planning model is a bi-level programming problem with a non-smooth lower level program which is difficult to be solved, we propose an efficient method with considering a smooth approximation function to solve it.

This qualitative multiple case study aims to explore the key knowledge that is transferred by predecessors (parents) to successors (children) in a family company. This knowledge becomes a resource to create the family company's competitive advantage. The research sample was composed of 23 participants from 13 family companies. The data were obtained through in-depth, semistructured interviews. The data were analysed using content analysis and then processed using a visual map and temporal bracketing. This study used source triangulation and member checking to ensure validity and reliability. The results show that the majority of knowledge transferred by predecessors to successors is tacit knowledge. Knowledge transferred by predecessors to successors includes knowledge of the product, knowledge of company management, technical knowledge, and philosophical knowledge.

Buyer-supplier relationships have always been an important component in the long-term success of supply chains. This paper constructs a non-parametric Hoteling's T2 control chart to ensure that supply chain partners in dyadic relationships have the same level of understanding about the relationship. The proposed method is helpful to identify any unusual behavior in the relationship before it becomes a real problem.

As one of the most important participants in construction industry, construction workers' unsafe behavior is very common on construction sites. From an individual level, this research aims to investigate the relationship among risk perception, risk propensity and unsafe behavior decision-making. A survey is conducted within first-line workers in Chinese construction projects. The results show that: 1) risk propensity is positively and significantly related to unsafe behavior, 2) risk perception is negatively and significantly related to unsafe behavior, 3) risk propensity is negatively and significantly related to risk perception, and 4) risk perception partly mediates the relationship between risk propensity and unsafe behavior. Thus, project managers should pay more attention to risk-seeking workers in order to reduce their unsafe behavior.

We consider the project scheduling problem where each project activity has a prescribed work content that must be completed by a so-called work-content resource, and the activities' resource usage may be varied over time. In each period, the amount of resources allocated to an activity must lie within a prescribed range and cannot be changed for a minimum number of consecutive periods. The amount allocated determines an activity's requirements for further resources. The activities must be scheduled such that the project makespan is minimized. For this problem, we devise an MIP-based heuristic that schedules the activities sequentially. To determine more efficient resource allocations among multiple activities, subsets of activities are rescheduled periodically. Our computational results for a standard test set from the literature indicate that the proposed approach provides very good feasible solutions for small-sized instances, and that it outperforms the state-of-the-art methods for large-sized instances.

This paper deals with the supply planning for two level assembly systems under stochastic lead time and random failure machine. The objective is to determine the optimal supply planning of the assembly system while considering the maintenance actions and then to study their impact on the optimal release dates for the components at level 2. The optimal supply planning minimizes the total cost which is the sum of inventory holding cost for components at level 1 and 2, assembly cost, maintenance cost, backlogging and inventory holding cost for the finished product. A mathematical model is proposed to compute the total cost and then to determine the optimal supply planning. Numerical results are presented to discuss the impact of maintenance actions on the optimal release dates.

This manuscript presents the results of experimental investigations which have been carried out to investigate the optimal parameter combination that results in the minimum axial process force (PF) in ultrasonic assisted face grinding (UAFG). A diamond grinding tool (diamond drill) was used in these investigations. The UAFG is a hybrid machining process, which has been used for the machining of advanced ceramic materials. The application of ultrasonic assisted grinding (UAG) is still limited, inter alia, because of difficulties during the selection of values for input machining parameters, such as: cutting velocity, feed rate, frequency of vibrations, and mounting torque, which is applied during tool clamping. The ultrasonic assistance provides advantages for the process course if the appropriate combination of input parameters is set on a hybrid/computer numerical control (CNC) machine tool. The PFs on the Ultrasonic 20 linear machine tool are measured using the Kistler 9256C2 dynamometer, and the optimal process parameter combination is calculated using the engineering robust design approach (ERDA).

In this study, we investigated the difference of luxuriousness between real model house and web-based model house. Living room as the most important residential space was targeted as an evaluation object. 6 living rooms and 9 elements contained in each living room were evaluated in terms of luxuriousness. Through independent samples t-test, we could examine that there were statistically significant difference in all elements in living rooms for both evaluations of real and web-based. Also we discovered elements that influence the luxuriousness of living room by multiple linear regression analysis. As a result, influential interior elements were extracted differently within two evaluation environments. From this points we concluded that independent strategies can be developed for web-based model house to enhance the luxuriousness, which has been widely utilized before people visit the real model house in terms of managerial point of view.

Recent years have been characterized by an increasing energy demand and by growing attention to energy production sustainability. For this reason, the number of plants powered by renewable sources has increased. Simultaneously, the energy sector has to face increasing uncertainty due to market liberalization. These factors has made it necessary for investors to find a proper evaluation method for their projects able to take into account also these aspects. This work tries to provide two original contributions: firstly, the creation of a model that helps the investor to understand which technology can best satisfy his energy need; and secondly, the implementation of the RO (i.e. Real Option) approach. To verify the consistency of the model, it has been applied to three different real situations.
