“…Cycle time, lead time, just-in-time, set-up time, delivery time and processing time are considered vital elements to boost productivity in the manufacturing sector (Andrade et al, 2015;Bhamu & Singh Sangwan, 2014). Ramachandran and Neelakrishnan (2017) pointed out that improving customer on-time delivery against the original promise date is crucial in the manufacturing industry. Thus, time is chosen as one of the criteria in this study.…”

Lean manufacturing is the optimal way of producing goods through the removal of waste and implementing flow, as opposed to batch processing. Many factories have transformed to align with the goal of lean manufacturing by minimising the resources of factories, such as less worker effort, less time and many more to lead to high efficiency towards good product quality and become highly responsive to customer demand. The condition of product and machinery, arrangement of inventory and equipment, the standard operation procedure of work and workers' safety awareness are the dominant elements in the leaf spring manufacturing process. Due to the crucial role that leaf springs play in the performance and safety of vehicles, it is crucial to eradicate any flaws in the designing and manufacturing processes. This study focuses on 5 core criteria, which are workers, time, safety, machines, and products that need to be enhanced. In the subgroup, each pair of sub-criteria will be compared regarding their importance with respect to each criterion. Analytical Hierarchy Process (AHP) is proposed to rank and aggregate the criteria based on their level of importance. The outcome of AHP showed that Safety (0.233) and Time (0.281) were the prominent criteria that need to be prioritised. Wear Personal Protective Equipment (PPE) (0.394), First Aid (0.324), Die and Pin (0.347), and Forklift Deliver (0.368) are the sub-criteria for safety and time. As a result, prompt and precise actions are needed to increase the quality and reliability of the product.

“…Lean manufacturing (LM) is an approved manufacturing concept that reduces the time between a customer's order and product build-to-shipment by reducing waste causes [Ramachandran & Neelakrishnan, 2017]. However, challenges include lack of awareness of appropriate lean technologies and people's attitudes [Ramachandran & Neelakrishnan, 2017]. To achieve continuous improvement, all functional units and systems must be evaluated.…”

Procurement activity in for an aircraft industry in Indonesia has suffered most during pandemic few years ago. The progress of Procurement at certain company is not that different. Moreover, one of the main problems in Procurement Division at the company is KPI On-Time Delivery target has not yet been achieved for aircraft commodities, especially for AEI. During these last 5 years, the procurement progress only achieved 48,5% on time, while the target is above 90% of total procurement activity. So far, mitigations has already been taken in order to reduce the delay rate. It give an impact, but the delay rate is higher than the target. The purposes of this study is to increase the On-Time progress and decrease the delay. this study uses conduct several analyses. Internal analysis using SWOT analysis method, while finding the root cause use method 5 Why’s Analysis method. Also, there are quantitative analysis and qualitative analysis. Qualitative analysis is done by using DMAIC Method to analyze the problem in a larger scope, while quantitative analysis is done to analyze the procurement data with Regression Analysis. The root cause of it was PR which could not be converted to PO because of the long-lasting RFQ and EQ process. The second root cause is miscommunication in the preparation of ordering aircraft materials. For the issue of the RFQ and EQ process is solved by developing and using e-RFQ Evaluation Tools to make sure that the quotation process and feedback from the supplier are done faster than using the manual method. For the miscalculation problem with improving teamwork and communication. The recommendation is to conduct research further regarding strategy purchasing.

“…On-time delivery (OTD) refers to the delivery of products that meet the quantity and quality requirements to customers in the period of the promised delivery date, which is a key metric to measure delivery performance [23]. OTD can ensure the reliability of delivery and, most importantly, customer loyalty as well as improve the reputation of enterprises and customer satisfaction.…”

Due to the influence of insufficient production capacity or shortage of production materials, production enterprises may produce products in advance or be backordered. In order to improve the adaptability of enterprises and reduce production costs, the impacts of early delivery and delayed delivery are analyzed, and the method to determine the loss threshold is put forward. Moreover, the maximum allowable shortage of customers with different tardiness is calculated, and the cost of delayed delivery and loss of sales is determined. Considering the production cost, raw material cost, inventory cost, staff cost, stockout, and lost sales cost, an early/delay multi-objective optimization model is developed for an aggregate production planning (APP) problem to minimize total production costs and instability in the workforce. Three algorithms and three different hybrid strategies are designed to solve the model. Finally, some test experiments are employed in order to validate the performance of the proposed evaluation of the three algorithms. The results show that: The method of determining the loss threshold can effectively reflect the double influence of customer satisfaction with waiting time and shortage quantity. The definition of unit tardiness cost reflects the law that it increases gradually with waiting time. The determination of the feasible range of product output and the number of workers in the workforce can reduce the search scope of the algorithm and improve the efficiency of the algorithm.
