Efficiency is the keyword in flow line analysis. This certainly holds for Heineken’s brewery in Netherlands, where retour bottles are being reused and refilled in high-volume production lines. These machine having its own task, speed and breakdown behavior. The bottles are transported on long conveyor belts from one machine to the next. Apart from transportation, the conveyor belts also act as buffers in case of machine breakdowns. However, long conveyor belts lead to long flow times, and they require space, material and high energy costs. Therefore, Heineken officials posed the question: Do we really need these long conveyor belts to achieve high throughput?
Remco Bierbooms and Marcel van Vuuren of CQM proposed a fluid flow model in “Performance Analysis of Exponential Production Lines with Fluid Flow and Finite Buffers” to predict the high-volume production of Heineken’s bottle lines. The team constructed an efficient, robust and reliable method to analyze this model and predict the performance of high-volume production lines toward more efficient production lines.
This issue is investigated in “Manufacturing System Design by Considering Multiple Machine Replacement under Discounted Costs”. This problem arises particularly when the product has a short life cycle and the time horizon is short. Thus, at the design phase of the manufacturing system, the workload of the equipment and accordingly its maintenance and operations costs are estimated based on the market demand forecasting and discount rate.
To define the problem Heineken officials posed the question: Do we really need these long conveyor belts to achieve high throughput? And to address this, Remco Bierbooms of the Laboratory for Industrial Mathematics Eindhoven (LIME), professor Ivo Adan of Eindhoven University of Technology, and Marcel van Vuuren of Consultan in Quantitative Methods (CQM) proposed a fluid for models in “Performance Analysis”. The problem was long conveyor belts lead to long flow times, and they require space, material, and high energy costs.
From our opinion there were 2 preliminary design criteria, such as design for productibility or disposability dan design for affordability. Productibility or disposability because this company was retour bottles are being reused and refilled in high volume production lines to improve efficiency from that productivity. Design for affordability because this company make fluid flow model to change the old system. That can reduce space, material, cost and affordability.
