File Name: production planning and inventory control in pharma industry .zip
Production control is the activity of monitoring and controlling any particular production or operation. Production control is often run from a specific control room or operations room. With inventory control and quality control , production control is one of the key functions of operations management. Production control is the activity of monitoring and controlling a large physical facility or physically dispersed service.
It is a "set of actions and decision taken during production to regulate output and obtain reasonable assurance that the specification will be met. Production planning and control in larger factories is often run from a production planning department run by production controllers and a production control manager. Production monitoring and control of larger operations is often run from a central space, called a control room or operations room or operations control center OCC.
The emerging area of Project Production Management PPM , based on viewing project activities as a production system, adopts the same notion of production control to take steps to regulate the behavior of a production system where in this case the production system is a capital project, rather than a physical facility or a physically dispersed service.
Production control is to be contrasted with project controls. As explained,  project controls have developed to become centralized functions to track project progress and identify deviations from plan and to forecast future progress, using metrics rooted in accounting principles.
Communist countries had a central production control institute, where the agricultural and industrial production for the whole nation was planned and controlled. Production control is just one of multiple types of control in organizations.

Motivated by a specific type of semi-batch biotechnology manufacturing, perfusion, we develop insights into biopharmaceutical production planning and inventory control in two areas. First, at the production site, we consider a continuous time infinite horizon lot-sizing model where a single product is manufactured on a single machine. Each time manufacturing restarts, a random production rate is realized, and production continues at this rate until the machine is shut down. Although the rate is random and chosen from an arbitrary set of random rates, it is known as soon as production starts, so this information could be used to determine when to stop production. Based on the production planning models, we show that given the objective of minimizing either average cost per unit time or total discounted cost, it is optimal to produce up to the same inventory level regardless of the realized production rate; even when backorder allowed, it is optimal to keep the same maximum backorder position. We also develop heuristics for the multi-product version of this production model. Next, for two-stage manufacturing supply chains, we extend this model to consider a specific characteristic of biopharmaceutical inventory planning -- both intermediates and finished goods expire, but the expiration "clock" is restarted at each stage.
In any manufacturing industry, production is the driving force to which most other functions react. The changing business environment in which pharmaceutical manufacturers are acting creates the need for more effective production processes planning and control methods, which are able to deal with uncertainties in internal processes and external deliveries. We will begin this article with the objective of PPC.
Underestimating will force you to short your clients, causing them to seek the products elsewhere. Overestimating will cost you money in either waste or storage. However, manufacturing is only one industry that relies on the appropriate balance between supply and demand. Whether you work in a bakery or in a technology firm, implementing material requirements planning MRP concepts can dramatically benefit your company.
If you work in manufacturing, you are certainly very familiar with this term, because it is very closely related to the production process. What is PPIC? PPIC is the practice of planning a manufacturing process and controlling the inventory of raw materials to be produced into finished goods. It is also a department in a manufacturing company that is responsible for planning and controlling a series of processes, making sure they run according to the predetermined plan. The PPIC department must work side by side with several other departments such as sales, procurement, and finance. The duties of a PPIC manager include:. PPIC plays a critical role in the smooth production process, because without proper planning and control, order fulfillment can be delayed and this can lead to customer dissatisfaction.

Но он тут же выбросил эту мысль из головы и перешел к главному. - А что с кольцом? - спросил он как можно более безразличным тоном. - Лейтенант рассказал вам про кольцо? - удивился Клушар, - Рассказал. - Что вы говорите! - Старик был искренне изумлен. - Я не думал, что он мне поверил. Он был так груб - словно заранее решил, что я лгу. Но я рассказал все, как .
- Получите удовольствие, профессор.
