Abstract
Production now requires the management of production processes and operations on the basis of customers’ demand to ensure the best combination of technology and humans in the system. The role of the humans in the production process is very significant for the production and quality of the product. The production system depends upon technology and human factors and is highly influenced by the working conditions of the workers, that is, work load, physical, dealings, job timings and so forth. In the current global economy, minimizing production costs is a serious priority for the industries. However, the costs of bad working conditions increase the intensity of the average stress among employees to cause extra costs by affecting the workers’ efficiency and products’ quality, which is invisible in the eyes of decision makers. This research identifies the cost of workers’ stress by developing a linkage between the economic benefits of the firms and the social upgrading of the workers. A numerical example of a production based system is performed to represent the real-time application of the proposed model. A sensitivity analysis is also carried out to quantify the impact of average stress among workers on the production system. Sequential quadratic programming is used to optimize the given nonlinear model for production planning. The optimal results influence ergonomics awareness and the relationship with the safety culture among managers in a firm. It is concluded that efficient and effective production cannot be possible without considering the working conditions of humans in the firm. Managerial insights are also generated from the implications of the results and sensitivity analysis.
Highlights
The production industry is considered one of the key indicators for the development of a nation.Human resources are a significant approach to a firm’s performance and it is believed that the most important assets of the firm are its people
The production stopped at t2, there will be no production and inventory is going down to zero during t3 .Theocratically, the total cost of production is the sum of capital cost, setup cost, manufacturing cost, holding, backorder cost, energy, inspection, reworking and recycling cost
This paper presents the impact of average stress on the production system with defective rate and workers’ efficiency as a function of workers’
Summary
The production industry is considered one of the key indicators for the development of a nation. Human workers require social development and deserve a good working environment to avoid workplace stress. It is the responsibility of the firm to provide a safe and healthy environment for the workers for better performance and productivity. Job stress can be defined as the occurrence of harmful physical and emotional response when the requirement of the work does not fulfil the capability of worker [7]. It is considered as a major challenge to the individual on the basis of mental and physical health, and it damages the organizational health [8].
