Lean Production

Critical path analysis identifies the most efficient and cost effective way of completing a complex project. The various activities which together will make up the project are identified, and the order of these activities are identified. Then, the duration of each activity is estimated and these factors are then arranged as a network or graph, showing the whole project from start to finish, and showing which tasks can happen at the same time. The sequence of tasks which have to be done one after another with no gaps in between is called the Critical Path.

Production practices have had an important role in satisfying the dynamic market. Many approaches have being developed in order to respond effectively to specific business requirements. In fact, some areas of management have focused its study on the overseeing, designing, and controlling the process of production in an effort to find the best methodology that ensures the business success and performance. However, complexities arise in this field because many variables such as costs, inventory, scheduling, suppliers, etc have to be considered in any business. Lean approach and the traditional approach are two points of view that aim to address this complexities, and those will be examined in this essay.

According to the main challenge of inefficient production, i.e. Michelin with improving production efficiency based on maintaining high quality, the theory of lean production system will meet the direction of development in Michelin production management. Thomas (1996) pointed that lean production can reduce overall costs, especially indirect costs, while remaining quality standards and reducing manufacturing cycle time. The goal of Lean production is maximization of enterprise interests, and timely manufacturing and eliminating all waste in the production process of raw materials procurement, storage, transportation, production and packaging(Heizer, Render and Munson, 2017). There are four elements from the lean production theory will be utilized to develop the analysis: value stream, pull production system, waste elimination and total quality management.

Critical path analysis is a method that is used to plan out the many activities involved in a project to be able to find the most efficient way of complete it and how to complete it on time.

Lean is defines the manufacturing philosophy that reduces the time between the shipping and customer demand, which based on the systematic method by eliminating waste, that means giving the customer what they want when they want it, and don 't waste whatever. Rahmana, Sharif and Esa (2013) suggested lean production is mentioned to improve the company 's performance from the philosophy in reducing waste in order. That means, lean system destination is the decrease cost by removing the non-value activities, which they are applying a category of tools and techniques for checking and eliminating defective in the production process. In the Evenort Company should emulate the five overriding principles of lean thinking in terms of implementing lean that there is guarantee the company has been driving correctly in the lean manufacturing (Cardiff 2015) as can show in table 1.

Critical Path Analysis is an effective and powerful method of assessing: Tasks which must be carried out Where parallel activity can be carried out The shortest time in which a project can be completed Resources needed to achieve a project The sequence of activities, scheduling, and timings involved Task priorities

The evolution of Lean production which can be also called Toyota Production system (TPS), manufacturing system introduced by automaker toyota, is contributed by two significant traditional method called Scientific management ( Taylorism ) and Mass manufacturing ( Fordism).

This written review details the two articles chosen for week 8 topic, lean manufacturing. The first article, titled Lean Production Practices for Efficiency Kocakülâh, M. C., Austill, A. D., & Schenk, D. E, published in Cost Management 2011, details the multiple elements that make up lean programs. The second article, titled Manufacturing’s Oversized Claims McCullough, M, published in Canadian Business 2011, details some of the pitfalls and down side to Toyota Production System lean elements.

This paper presents a review of the use of Lean Production in a process plant. It defines lean production as a process putting into consideration the history and the reason it was formulated. It also considers the application, benefits and the barriers to the effective maximization of the process.

Lean manufacturing is a production practice that considers the expenditure of resources for any goal other than the creation of value for the end customer to be wasteful, and thus a target for elimination. Working from the perspective of the customer who consumes a product or service, "value" is defined as any action or process that a customer would be willing to pay for. The goal of Lean is to becomes the creation and maintenance of a production system which runs repetitively, day after day, week after week in a manner identical to the previous time period. Lean is actually the set of "tools" that assist in the identification and steady elimination of waste. As waste is eliminated quality

❖ Mechanical Design: Jabil Circuit’s mechanical engineering design team involves in three-dimensional design and analysis of electronic and optical assemblies using modeling and analytical tools. It also involves in industrial design, advance mechanism development, and tooling management.

The automotive industry continues to grow every day. Companies are always coming out with new technology for cars to better their product. In order for these companies to keep a competitive advantage they most implement different types of manufacturing processes. One of these manufacturing processes is lean manufacturing. Sundar, Balaji and Satheesh have done research on lean manufacturing, and they define it as the elimination of waste by determining value added activities and non-value added activities. Non-value added activities consist of transportation, inventory, motion waiting, overproduction, over processing, and defects (2014). Elmoselhy has found multiple tools to be used to implement lean manufacturing. Some of these tools are: 5S, Value Stream Mapping, Single Minute Exchange Die, Kaizen, and Autonomation. This list does not include all of the possible ways to implement lean manufacturing, but gives a brief introduction to a couple. The 5S stands for Sorting, Setting, Shining, Standardizing, and Sustaining (2013). This paper will discuss one of the five S’s, which will be standardizing. Also, this paper will also go into detail about how an automotive manufacturing company uses Single Minute Exchange Die, and some other aspects of lean manufacturing such as visual control and environmental management. Because lean manufacturing can be implemented in many different ways this paper

The concept of "lean production" was first introduced in The Machine that Changed the World (Womack et al., 1991) to refer to a new way of looking at the manufacturing enterprise. It was distinguished from mass production by its single-minded focus on eliminating waste in all aspects of the enterprise.

The right produce process will produce the right results: Create a continuous process flow to bring problems to the surface, use visual control so no problems are hidden, and the standardization of work duties is to empower the employees and continuous improvement.

Lean Manufacturing is primarily concerned with removing waste from the production process. (Pham, Dimov and O 'Hagan, 2001)
