JIT is a great technique that assists manufacturing enterprises in improving efficiency in production and also has quality implications. It is usually implemented along with Kanban. Kanban is a key technique to involve people in the Lean process, from suppliers to customers. It helps eliminate the waste from inventory and overproduction. In addition, Zero Defects focuses on getting the product right the first time rather than spending extra time and money fixing poor quality products. The Zero Defects system reinforces the notion that no defect is acceptable, and encourages people to do things right the first time. The 5S philosophy relies on standardization and the 5S system focuses on sort, set in order, shine, standardize, and sustain. It is used to eliminate waste in work areas (MindTools 2016).

Inspection and Measurement. With a growing interest in product quality, the focus has been on “zero defects.” However, the human inspection system has somehow failed to achieve its objectives. Robot applications of vision systems have provided services in part location, completeness and correctness of assembly products, and collision detection during navigation. Current vision systems, typically two-dimensional systems, compare extracted information from objects to previously trained patterns for achieving their goals. Co-ordinate measuring machines (CMM) are probing machining centers used for measuring various part features such as concentricity, perpendicularity, flatness, and size in three-dimensional rectilinear or polar co-ordinate systems. As an integrated part of a flexible manufacturing system, the CMMs have reduced inspection time and cost considerably, when applied to complex part measurement.

Zero defects is a management tool which reduces defects through prevention. It may be defined as a state where defects are eliminated and reduced to zero. This philosophy was introduced in 1960s by Philip Crosby. It is used by automobile industry for first time. Zero defects concepts mean no wastage in production. A lot of objections and criticism has been faced by the concept. Some researchers say that there cannot be a state of zero defects. Zero defects in quality management refers to a state where waste is eliminated and defects are reduced. It means ensuring quality standards and reducing defects to the level of zero in projects.

Lean manufacturing refers to a group of manufacturing practices that focus on the reduction of non-value-added activities, including in pull-production systems, process variance reduction, quality management, and people involvement (Shah and Ward 2003; Melin and Barth 2018). Pull-production refers to a manufacturing system that produces only what is demanded by the customer, using a series of signals (Sugimori et al. 1977). Process variance reduction is part of a comprehensive manufacturing strategy to reduce process variability through process set-up time reduction and total productive maintenance (Kannan and Tan 2005). Quality management strives for zero defects through process continuous improvement (Möldner, Garza-Reyes, and Kumar 2020). People (i.e. employee) involvement is a key lean practice that enhance other lean practices by including proactive problem solving, people motivation, and teamwork (Martinez-Jurado and Moyano-Fuentes 2014). The current study focuses on the internal orientation of lean, and thus we conceptualise lean manufacturing as internal lean practices (ILP) or the implementation of a group of manufacturing practices focussed on the reduction of non-value-added activities from organisations’ internal manufacturing operations (Chavez et al. 2015, 2020).

Currently, the manufacturing supervisor is also working on the manufacturing process. It is considered that he should work only on supervising the process. It would improve the process quality and control, with the overall goal to achieve “zero defects.”
Optimal decision of an economic production quantity model for imperfect manufacturing under hybrid maintenance policy with shortages and partial backlogging

In nowadays market competition, many companies are seeking competitiveness by emphasising the cost, quality, flexibility, and service as well as other order-winner performances. The lean production (or JIT production) is known as one of the most competitive manufacturing systems in cost efficiency and customer responsiveness. Lean production emphases on the philosophy of two zeroes – zero inventory and zero defect. Zero defect means that the product quality is perfect without defect, but zero defect quality comes from zero-defect work and zero-defect equipment (zero faults). In order to obtain zero defect equipment, maintenance actions are needed, for example, Toyota promotes the total productive maintenance (TPM), which especially emphasises on preventive maintenance. However, equipment maintenance has two-side impacts on production. On one hand, maintenance improves equipment performance and makes equipment at a good status to produce a high quality product, on the other hand, it impacts the production output (interfering the production). Consequently, maintenance has an influence on the production decision, such as production lot size decision. Traditional economic production quantity (EPQ) model assumes that the production process is perfect and no imperfect items are produced. However, in practice, the production facility is not failure free and the product quality is also not always perfect. Therefore, from the theoretical as well as practical perspectives, it is quite significant and meaningful to study the joint optimisation of production inventory and maintenance policy. In this paper, we study the decision problem of economic production quantity for an imperfect production system under hybrid maintenance policy with consideration of the shortages and partial backlogging. We assume that the production process is imperfect stemming from the machine reliability and the probability of out-of-control, a hybrid maintenance policy combined of emergency maintenance and preventive maintenance is executed during each production run. The proposed decision mechanism will be helpful for practitioners to improve the production and maintenance management.
