本文應用Petri Net 資訊流結合Timed Petri Net 理論、Stochastic
Petri Net 理論、加工工件之暫存區Petri Net (Petri Net Modeling of
Buffers)與整合製程規劃及動態排程之牙科燈之創研流程混合雲流程
建構，以及建立計算數據及時間參數的生產時間之牙科燈創研流程設
計與製造流程模型。本文以專利號US7665875 B2 的205 號與400 號
兩種不同之牙科燈零件，先規劃出工廠佈置圖，並以兩種零件建立適
當之製程規劃及替代製程規劃。替代製程規劃包括了加工機台異常需
短時間修護、以及加工機台較長時間的故障等情形下可以選擇使用的
替代製程規劃。並依不同製程規劃建立包括等待時間、搬運時間、加
工時間等參數計算出加工零件所需之最短總流程時間(Total Flow
Time)的理論公式。從本文之研究中結果看出，因不同零件數量與加
工順序皆會影響加工之總流程時間。所以要先確認零件數量之後才會
模擬計算出最短之總流程時間的製程規劃與加工排序。當不同加工機
台故障時，可能選擇替代製程規劃或等待機台維修時間後繼續加工，
因零件數量不同與加工順序的變化，當不同加工機故障時，本研究發
現有的是等待維修後繼續加工的總流程時間最短，而有的是直接使用
替代製程之總流程時間會最短，故可因應不同狀況選擇等待或變更製
程。本文又應用Petri Net 理論與Petri Net 數據流計算建立具有計算
數據之流程模型，應用於牙科燈之結合修正式Fuzzy DANP 之修正式
Fuzzy VIKOR 方法，來進行評選出優先產品功能改善方案。本文亦將
Petri Net 資訊流相關理論、設計及製造流程規劃所需的相關知識，及
結合修正式Fuzzy DANP 之修正式Fuzzy VIKOR 等設計與製造相關
理論知識與相關專利知識，輸入擴充至創研流程相關理論知識私有雲
及牙科燈專利知識庫中，如此可增加牙科燈相關知識，讓使用者易於
學習，使其能應用於創研流程架構模型。

The paper applies Petri net information flow, combines timed Petri net
theory, Stochastic Petri net theory and Petri net of temporary storage area
of processed workpiece (Petri net modeling of buffers) with establishment
of hybrid cloud procedure of innovative research procedure of dental light
that integrates process planning and dynamic scheduling, and establishes
the dental light’s innovative research procedure design and process flow
model of production time for calculation data and time parameter.
The paper, taking two different dental light parts, No. 205 and No. 400
of patent No. US7665875 B2 as the examples, firstly draws the factory
layout plan and then uses the two kinds of parts to establish suitable process
planning and alternative process planning. The alternative process
planning includes the optional alternative process planning under the
circumstances that the processing machines with abnormalities have to be
repaired within a short period of time and the processing machines are
malfunctioned for a longer period of time.
According to different process plans, the paper establishes the
parameters of waiting time, moving time and processing time to calculate
the theoretical equation of the shortest total flow time required by the
processing parts. As seen from the research results of the paper, since the
difference in quantity of parts and the order of processing would both affect
the total flow time of processing, quantity of parts has to be confirmed
before simulation of the process planning and processing scheduling that
calculate the shortest total flow time.
When different processing machines are malfunctioned, alternative
process planning can be selected, or processing can be continued after
waiting for the maintenance time of the machines. Due to difference in
the quantity of parts and change of the processing order, when different
processing machines are malfunctioned, the paper finds that in some cases
the processing continued after waiting for maintenance has the shortest
total flow time, whereas in other cases the alternative process directly used
has the shortest total flow time. Therefore, based on different situations,
we can choose to wait or change the process.
The paper employs Petri net theory and Petri net dataflow to calculate
and establish a procedure model with calculation data for application to
modified fuzzy VIKOR method of the combined modified fuzzy DANP of
dental light, so as to select a prioritized improvement project of product
function.
The paper also enters the related knowledge required by the related
theory, design and process planning such as Petri net information flow, the
knowledge of theories relating to design and process planning, modified
fuzzy VIKOR of the combined modified fuzzy DANP, and the related
knowledge of patents of dental light, and then expands them to private
cloud of the related theoretical knowledge of innovative research
procedure and the knowledgebase of dental light patents.In this way, the
related knowledge of dental light can be increased, enabling users to learn
the knowledge easily, and making the knowledge applied to the innovative
research procedure framework model.
