“…Order fulfillment management is important for the industry because it is possible to measure the amount of delivered and late products, to quantify in monetary value the penalties and to analyze the causes of delays [7], [8] For this, tools such as Value Stream Mapping (VSM) are used as a starting point, since this tool is responsible for capturing the information flow of the processes and their variables such as Work In Progress (WIP) and Lead Time to determine if the quantity of products will be finished on the planned date [5]. Evidence that supports this is the case of an automotive company where there are late deliveries due to a high rate of defective products, to reduce this, they use the Lean Manufacturing philosophy through a VSM, by identifying the failures in the processes and taking corrective measures, the WIP, Lead Time and OTD indicators achieved an increase of 94.53%, 98.25% and 6.38% respectively.…”

The plastic sector sustains an important growth based on production worldwide and nationally during the last years. However, this growth in production can be affected by the various problems that the sector sustains, harming the availability of plastic products and thereby affecting customers, this impact is reflected in customer losses due to the non-fulfillment of orders or additional payments for penalties imposed by them. In this context, companies in the plastic sector aim to reduce machine downtime rates to increase availability and thereby maintain smooth production and thus increase the order fulfillment rate. After the above, in the research, the problem that generates a low rate of order fulfillment is due to the constant blowing machine shutdowns in the plant. Therefore, it is proposed to design a model based on the Lean Manufacturing philosophy, using tools such as 5S, SW, TPM and SMED, based on applications of the Lean Green philosophy; with the aim of reducing stops in the blowing machine making it more efficient and environmentally friendly. This research emphasizes the most representative product of the company, the drums, developing the diagnosis in the blowing process, which, the root causes were quantified with respect to the main problem, through the tools of the Lean Manufacturing philosophy it is proposed to address each cause and mitigate them. Finally, the model that has been proposed manages to reduce the rate of machine shutdowns by 55.48%, giving greater availability to the blowing machine and with it a better production flow, which generates an increase in the order fulfillment rate by 74.59%.In this way, a precedent is achieved in the plastic sector regarding the improvement of blowing processes.

“…In this way, several authors assure that the role of maintenance is relevant when seeking to improve production standards such as: equipment availability, quality, and performance. According to several authors, the application of TPM has increased the overall efficiency of equipment in a spinning plant, a forging workshop, a clutch manufacturing company and a plastic bottle producer by 10.93%, 17.08%, 5% and 16.2%, respectively [4], [16], [23]- [25].…”

The plastics industry is important in the world due to its recurrent use in daily life and the supply it provides to other sectors such as medicine, transportation, health. Previous studies show that the average difference in global efficiency between the manufacturing industry and the World Class ranges between 15 to 25 percentage points, also affecting the plastics sector. The case study presents a gap of 17% regarding this metric in the thermoforming line. This efficiency gap has had an impact on cancelled orders, which generate 18.8% of annual sales losses. During the analysis it was determined that availability losses are generated by constant machinery breakdowns and quality losses are caused by the high rate of nonconforming products. Thus, in view of the scarcity of efforts in the sector, an efficiency maximization model is proposed that combines the management of time and machinery with the quality associated with the process. To this end, the integration of tools such as 5S, autonomous and planned maintenance to reduce unscheduled stops and standardization under a continuous improvement framework to reduce the sources of quality loss is proposed. In this way, an improvement of 12.15% in the efficiency of the line is achieved, increasing by 3.36% and 10.96% in the Availability and Quality indicators respectively for the M4 thermoforming machine.

Overall equipment effectiveness (OEE) is a key performance indicator used to measure equipment productivity. The purpose of this study is to review and analyze the evolution of OEE, present modifications made over the original model and identify future development areas. This paper presents a systematic literature review; a structured and transparent study is performed by establishing procedures and criteria that must be followed for selecting relevant evidences and addressing research questions effectively. In a general search, 862 articles were obtained; after eliminating duplicates and applying certain inclusion and exclusion criteria, 186 articles were used for this review. This research presents three principal results: (1) The academic interest in this topic has increased over the last five years and the keywords have evolved from being related to maintenance and production, to being related to lean manufacturing and optimization; (2) A list of authors who have developed models based on OEE has been created; and (3) OEE is an emerging topic in areas such as logistics and services. To the best of our knowledge, no comparable review has been published recently. This research serves as a basis for future relevant studies.
