Today, improving machine availability is vital for industries to compete in the global market. Spare parts play an essential role in the maintenance and repair of equipment, but planning an extensive network in strategic industries with various spare parts can be very challenging due to the existence of different decision factors. The spare parts supply chain deals with inventory management issues, which necessitates considering the related decisions such as determining the stock level and order quantity. Moreover, demand uncertainty and long supply time make decision-making more complex. This paper presents a repair and supply planning model for repairable spare parts while considering a modified formulation of demand uncertainty to minimize costs. The model determines the optimal stock level, lateral transshipment, assignment of spare part orders to suppliers, equipment to repair centers, and the number of intervals over the planning horizon used in demand estimation. This research contributes to the literature by integrating recent decisions, using demand approximation by piecewise linearization, and considering backorder in warehouses evaluated by queuing models. A hybrid approach, including heuristic and genetic algorithms, is used to optimize the model using data from an oil company. The results show that using piecewise linearization and integrated repair and supply planning decisions optimizes costs and improves performance. Also, the availability is affected by the demand estimation, which necessitates precision prediction.

Food industry has vital importance globally in which supply chain sustainability plays a key role. Therefore, the objective of this study is to examine the role of passion, planning, goal setting and target achievement in a sustainable supply chain. This study examined the relationship between passion, planning, goal setting, target achievement and sustainable supply chain among the food industry of Indonesia. Questionnaire survey was preferred, and 500 questionnaires were used for data collection. Findings of the study concluded that passion has a positive role in target achievement and an insignificant effect on sustainable supply chain. Planning has a positive effect on target achievement and sustainable supply chain. Moreover, goal setting has a positive role in target achievement and no role in supply chain. Furthermore, target achievement has a significant mediating role. Finally, the relationship between passion, planning, goal setting, target achievement and sustainable supply chain has valuable contributions to the literature.

his paper investigates normalization and psychometric properties of career skills confidence inventory. For this purpose, we use Betz’s questionnaire [Betz, N. E., Harmon, L., & Borgen, F. (1996). The relationships of self- efficacy for the Holland themes to gender, occupational group membership, and vocational interests. Journal of Counseling Psychology, 43, 90-98.], which consists of 60 questions in three groups of self-awareness, exploration and planning. The study distributes the questionnaire among 600 randomly selected students and analyzes the feedback using Pearson correlation ratios. The results indicate that there are some positive and meaningful correlations between three component and career counseling. There are also positive and meaningful relationships among three components of self-awareness, exploration and planning.

In today’s turbulent and competitive world, strategic planning plays an important role for the
success of firms. Despite the fact that there are literally numerous models proposed for different
companies in various states and structures, the possibility of using strategic planning for
startups has never been seriously considered. In this paper, we present a survey by asking
experts to find out whether strategic planning is suitable for startups. We also propose a model
for strategic planning in startups based on the strategic planning models for small businesses
and entrepreneurship concepts. The model is similar to other models and what differentiates
this models form other approaches is the methodology used for internal and external analysis
and the parameters taken into consideration. The proposed model is examined on an Iranian
food packaging industry for validation. The preliminary results indicate that the success of
startups depends on two sets of parameters: “entrepreneurial opportunities” and “competitive
advantages and entrepreneurial characteristics”.
