THE MODELING AND ANALYSIS FOR THE LEAD TIME
OF MAKE TO ORDER MANUFACTURE PRODUCTS BASE
ON TIMED TRANSITION PETRI NET
ABSTRACT
With the developing of market economy, and under the situation of
global economic competition, Companies today face a multitude of supply
chain challenges that did not exist a decade ago. Increasing supply-and-
demand uncertainties, the accelerating pace of product and technology
changes and the electronics industry's continuing "disintegration" all add
complexity. A successful supply chain strategy requires distinct
capabilities to meet these challenges. As companies increase their product
variety and customization and penetrate new markets, they need to
improve their forecasting, production scheduling and inventory planning;
at the same time, the serious competition in the marketing area caused the
change in the marketing mode, more and more enterprise changed their
production from Make-to-Stock to Make-to-Order, when new orders
come, the managers need to know the accurate delivery date to help them
make sale scheme to meet the customer’s requirement and win the deals
from the competitors. It is to say that, in order to promote their competitive
position, enterprises need a path that can forecast the product delivery lead
time in a quick, real-time and accurate way.

In this essay, according to the theories of the Petri net, establish the
timed transition Petri Net (TTPN) mathematics model of make-to-order
product manufacturing for the customer-distribtion centor-supply business
model of author’s company in HPSim program, base on the analysis of the
real order delivery cycle time to help establish the lead time prediction
simulation mode of product delivey for new customer orders. That method
is a graphical and intuitive, easily of design and simulation manner, and it
is a quick, real time and accurate tool with meeting the requirement to
prodict the product delivery lead time.
The author, according to the analysis and researches of the actual cases,
estiblish the basic forecasting timed transition Petri Net model for make-
to-order product delivery lead time, at the same time in study course,
discovered the existent problem of the Petri net software and provided
some opinions for further study.
Key Words: Lead Time, MRP/ERP, SCM Petri Net (PN), Timed
