At Controls Manufacturing Community List Dear All Can anyone send me a single page comparison or presentation on PLC Vs DCS as on today's date? I shall be thankful for your kind inputs. Thanking you, Regards, (Name removed) Control System Staff Engineer
Introduction • To partial fulfillment of the requirements for the degree of Master of Business Administration in Information Management at the Newport Business Academy and Newport International University, I decided to work out a thesis proposal with the title “Selection and decision-making criteria for a Distributed Control Systems” in the process industry.
The project framework (1) • For the control of the chemical processes in the process “chemical” industry Distributed Control systems (DCS) are applied. These systems are the heart- and nerve system within these factories. • The choice of DCS for a concern is a matter of strategic importance. • High demands are made to the availability of a DCS and if the concern made a choice, she is committed to it for a lengthy time. Replacing a DCS is a very valuable matter because of the arisen production loss at a reconstruction for example. • The service costs of a DCS could be a multiple amount of the initial investment during the life span.
The project framework (2) • The process industry in the world for approximately spends 45.8 billion dollar per year at the top 50 suppliers on process control systems (included DCS).(2004 data) • The expenses of these investments often amount to more than 1 million Euro by per system. • The selection process generally varies from 12 up to 24 months. • At large DCS projects there sometimes are investments of more than 45 millions Euro. • The total expenses, which are involved with the selection of one investment, amount more than 100,000 Euro per system. To earn an order, the marketing/ sale expenses generally are more than 50.000 Euro at a supplier.
The project framework (3) • Local employees of the establishments are involved frequently in the choice for a system. Because of the fact that this investment only takes place every 10-15 years, they are lacked from experience and methods to be able to take this kind of decisions. The consequence is that the choice for a certain system is not always univocal at this moment and the relation between a business case, a chosen solution, and the selection process isn’t always there. This study has to contribute that we make the choice of a system in a more univocal way and the decision-making becomes more transparently.
Main objectives The goals of this research is: • The improvement of model-based consideration concerning a selection of a new distributed control system (DCS), by making an analysis of selected criteria within the “chemical” industry to choose a DCS and to establish an investment/ selection model with these insights/ ideas. • So that future investment can be bought faster and the decision-making will be more transparent.
Study • Define the core selection criteria and their priorities for the purchase of a Distributed Control system (DCS) in the chemical industry and a design a decision-making model so that the decision-making for new systems more balanced more consequent and faster can be carried out. • Interview employees who are involved in the purchase decision of DCS within large DCS using companies like Alcoa, Akzo Nobel, BP,, Dow, Dupont, Exxon Mobil, DSM, Lyondell, P&G, Sabic, Shell etc. • Also account managers and marketing managers of the chosen DCS have to be involved in this research.
The areas of the study (1) • What is the business case of your investment in a new DCS system? • What is the reason for this investment (migration, replacement or a new installation) and what are consequences of the choice of system? • Which DCS supplier knows the person who is concerned in the company purchase of a new system? • What decides whether the DCS supplier comes on the Big List for further evaluation? • What decides whether the DCS supplier comes on the Short List for further evaluation?
The areas of the study (2) • Which staff functions are involved in the selection? • At which components do these people pay attention and which priority do they give to the different components? • Is there a difference between the ideas of DCS suppliers and users concerning these criteria?
