- Description: The current business environment in pump manufacturing companies is characterized by markets facing fierce competition. Customer expectations as a result are becoming increasingly higher in terms of quality, cost and delivery dates. These expectations are even worse due to rapid development of new information and communication technologies which provide direct connections between companies and their clients. Therefore, companies must have powerful “planning and controlling” mechanisms at their disposal. To achieve this, companies rely on a number of functions including production scheduling. Production scheduling strategies and disruptions management in pump industry are investigated, followed by a new-fangled concept suitable for addressing problems considered herein. Slot allocation process which starts by assigning slot number and/or confirmed order and ends when it is accepted into the queue by operations planning is presented. We further examine and relate market needs with manufacturing capacity available and supplier capacity by employing basic theory of work measurements, e.g., TAKT time, etc.

- Description: Production scheduling which is a part of the planning and control of production units lies at the heart of the performance of manufacturing organizations. Production scheduling determines organizational performance. The need for efficient scheduling has greatly increased in recent decades owing to market demands for product quality, flexibility and order flow times, and other measures. However, although scheduling research activities have in the same period moved from purely academic exercises to serious attempts to solve practical problems in companies, successful implementations of scheduling techniques in practice are still scarce [1-6] and less attempt on solving the same from an economic perspective. In many companies, scheduling is still a typically human domain. However, the task of scheduling production units can become very complex. Humans are not very well equipped to barely control or optimize large and complex systems without computational tools, and the relations between actions and effects are difficult to assess. This paper will focus on problems that are related to the complexity of scheduling in practice. Scheduling based on this technique is often changed by the scheduler due to random disruptions or are not carried out exactly as preplanned on the shop floor. Because of the complex production processes, schedules are often difficult to assess mainly in terms of production cost. This paper takes a leap approach by assessing production performance in terms of cost. A new criterion of optimality is also proposed and used. This criterion is termed “total opportunity cost” and takes into account the different single criterion in a weighed term.

- Description: Abstract: These days, in the extremely competitive nature of business, nearly every big business has to reap the benefits of investing in improvements of its supply chain. The beginning of the upgrades is considered together with the examination concerning profits and most organisations have addressed measures that a supply chain execution and monitor changes in order to drive the benefits of their business. While execution estimation is basic, most organisations either measure excessively or pay little attention to supply chain. Different weaknesses may incorporate; an excessive number of measurements, disconnected measurements, clashing measurements, obsolete measurements, temperamental information, and absence of possession, among others. Some organisations measure incorrect variables in their pursuit of their objectives. This is detrimental to the realisation of these objectives and this affects the organisation. Framework estimations lead to improved framework. "Estimation is the initial step that prompts control and in the long run to progress. In the event that you can't gauge something, you can't get it. On the off chance that you can't get it, you can't control it. On the off chance that you can't control it, you can't improve it" (Harrington, 2012)... , M.Ing. (Quality and Operations Management)
