Abstract :
The purpose of this paper is to apply TRIZ for solving the GSC problems in Sobhan
oncology pharmaceutical firm. First, a review of the past papers of TRIZ based methods
to GSC problem resolution is presented. The TRIZ contradiction matrix tool which was
applied to the specific problem brings many benefits e.g.: being rapid acceleration in
solving the problem. Moreover provides repeatability, predictability, reliability and also
cut costs and times due to its structure. The situation is based on a manufacturing process
problem. To recognize, understand, analyze, and solve the problem, the author identifies
six steps which are applying Fish bone diagram, illustrating non-existence of
optimization, showing the contradiction by classical TRIZ system of contradiction model,
Linking the Contradiction, decision and evaluation space, and applying TRIZ
contradiction matrix to solve the problem. According to the result of distributive
questionnaire the problem is related to ineffective pressing process of one of tablets
which is named Flu amid. According to the problem which is technical and has technical
contradiction, TRIZ contradiction matrix is chosen. After analyzing the principles,
according to comparison of profit and loss, following the principle 35, by changing
physical state in process condition could be made to resolve problem. Instead of granule
powder, the liquid one can be applied which will be formed in low temperature to solid
one. As a result, no wasting time could be happened.
To this end, although TRIZ contradiction matrix provides 39 general parameters to solve
technical contradiction (Karimi, 2007), none offers a specific framework which includes
details for each parameters.
