A Study On The Production System Improvement Of R
Company
Abstract
With the improvement of domestic gelatin enterprise research and development
ability, continuously improve the quality of products, and other multinational companies
market penetration, industry competition is fierce. Gelatin industry is a typical
labor-intensive, gelatin production system is the core part of the gelatin enterprise which
most of the equipment by manual control in traditional production line, Companies must
actively seek to improve for long term sustainable development of the enterprise in
competition. The thesis studied R company, how to improve the production system by
optimizing production process, control system, production management and organization,
so as to reduce human cost, increase production efficiency and improve product quality.
Firstly, the thesis analyse process optimization and related theory of DCS control
system, mainly introduces the meaning and the analysis method of industrial engineering,
the purpose and design step of process reengineering, hardware structure, software of DCS
control system and the development trend of DCS control system.
Secondly, introducing R company profile and analyzing problem which production
system exist in current situation, and then puts forward improvement program, including
improvement principles and ideas, improvement of content. The obstacles in the process of
production system improvement at the same time analyzed one by one, and put forward
corresponding countermeasures.
Finally, analyzing data between before and after production system improvement
with comparison analysis method, mainly focus on human cost, product quality and
production efficiency three aspects, conclusions as following:
(1) We can make the gelatin production of labor-intensive enterprises to the
technology-intensive enterprises come true by optimizing the production process and
organization management.
(2) Process automation of production system make the production control parameters
more stable and product quality improved steadily through precision testing instrumentIII
equipment and reduce artificial misjudgment interference.
(3) Throughout the entire process, through the control system to realize the automatic
program, seamless each working procedure, simplify the work link to optimal allocation of
resources, greatly improve production efficiency.
(4) Removing lots of middle links after production system improved, the quality
requirement of operator increased and need comprehensive ability although the number of
people is reduced.
