For more than a century, forecasting models have been crucial in a variety of fields. Models can offer the most accurate forecasting outcomes if error terms are normally distributed. Finding a good statistical model for time series predicting imports in Malaysia is the main target of this study. The decision made during this study mostly addresses the unrestricted error correction model (UECM), and composite model (Combined regression—ARIMA). The imports of Malaysia from the first quarter of 1991 to the third quarter of 2022 are employed in this study’s quarterly time series data. The forecasting outcomes of the current study demonstrated that the composite model offered more probabilistic data, which improved forecasting the volume of Malaysia’s imports. The composite model, and the UECM model in this study are linear models based on responses to Malaysia’s imports. Future studies might compare the performance of linear and nonlinear models in forecasting.

This paper deals with the modeling, analysis and optimization of a specific kind of real industrial problems. This class of problems is known in the literature as Cyclic hoist Scheduling Problem （ChSP）. In such class of problems, several jobs have to flow through a production line according to an ordered bath sequence. The ChSPs appear in the manufacturing facilities to achieve a mass production and to search a repetitive sequence of moves for the hoist. In this paper, we develop P-Temporal Petri Net models to represent the behavior and validate certain qualitative properties of the basic production line. Afterward, complex configurations of the production line are modeled and their properties such as reachability of desired functioning （cyclic operation）, deadlock-free, resource sharing and management are checked and validated. A mathematical analysis and a simulation study of all proposed Petri net models are carried out using mathematical fundaments of Petri nets and a Visual Object Net ＋＋ tool. The second part of the paper deals with the development of a mixed integer linear programming models to optimize processing of each line configuration. Optimal manufacturing plans of the studied system with cyclic processing sequences are defined and the feasibility of optimal cyclic scheduling of each configuration is proved.

Stress has become a worldwide phenomenon, which happens in various procedures in every organization. Nowadays, employees at the workplace generally work more extended time than before, as the responsibilities increase the tension and stress increase and it requires to employ themselves even more energetically to encounter increasing expectations about workplace activities. Omolara (2018) described workplace stress as psychological and physical responses that happen in an individual as an outcome of existence unable to cope with the stresses being made. According to Swanepoel (2017), business-related to pressure and theme has expanded considerably in the region of word-related well-being throughout the four decades. These creators were of the feeling that the world, particularly the cosmos of work and business, has gotten gradually subject to rapid altering powers like prolonged competition, the weight of value, development, and an expansion in the movement of doing business. The requests on representatives developed similarly significantly, and this put pressure on workers. Aside from the stress that arises from the work situation, different fountains of stress could identify with discrete influences, for example, relatives with others and operation of free time. Stress can next be depicted as the unfavorable mental and physical responses that happen in a person because of their powerlessness to adapt to the requests being made on the person in question. Griffen, (2018), That is pressure from special requirements on an individual. It is noticed that stress isn't downright awful;it is an opportunity when it offers expected addition. In any circumstance, whatever its tendency, it typically starts when individuals are put in a workplace incongruent with their work style and or personality. It becomes disturbed when people determine that they have or can practice little command over it.

长期以来,坦桑尼亚一是东非外交事务的前沿阵地,并在非洲东部地区地区发挥了领导性作用。自2004年以来,坦桑尼亚的外交政策逐渐由解放外交转向经济外交。坦桑尼亚对肯尼亚的外交政策对两国人民生活的各个方面都产生了影响,其中包括政治影响、社会影响和经济影响。坦桑尼亚的外交政策主要体现在它会向肯尼亚公司的投资、贸易和安全做出指示。坦桑尼亚的外交政策为巩固睦邻政策、促进非洲统一、加快工业化进程与经济发展指明了方向。在东非国家中,肯尼亚是坦桑尼亚的重要合作伙伴之一,因为与其他东非国家相比,肯尼亚对坦桑尼亚的贸易额和投资额要高出许多。坦桑尼亚政府制定了法律和法规来规范与肯尼亚的跨境贸易,并为肯尼亚政府和私人投资者在坦桑尼亚的投资创造了有利的环境。坦赞两国政府都致力于解决其经济问题,进一步促进两国经济的发展。坦桑尼亚对肯尼亚的外交政策将东非地区的的工业化和区域建设作为重中之重。坦桑尼亚的外交政策积极解决了肯尼亚不安全的困境,并与肯尼亚携手共同解决与肯尼亚部落、野生生物走私和矿物开采问题有关的犯罪。因此,坦桑尼亚对肯尼亚的外交政策不仅为该地区的经济发展做出了巨大贡献,也为维护东非地区国家之间的团结、和平与安全做出了巨大贡献。
