延展式供應鍊成員間的「資訊分享」是一項重要的課題，當吾人談論至此時，每一位成員需使用相同的「語言」。而在此之前，其必須先對於整個系統有著相同方式的認知。我們將會採用Cognitive Work Analysis（CWA）之前兩個階段-- Work Domain Analysis與Control Task Analysis—以達到此一目標。之後，我們將著重在「供應鍊配置」此一主要問題上。 我們視延展式供應鍊為單一系統，並嘗試發展一方法論，能夠確保這樣的系統運作是可預期的且穩定的，然而當系統越趨複雜，越難以認知、了解隱藏於系統的知識與資訊處理的過程，所以我們應用了CWA中的Abstraction Hierarchy (AH) 與Decision Ladder (DL)以挖掘其中的知識與與資訊處理過程，當延展式供應鍊之組成改變時，應用系統動態學探討整個延展式供應鍊之長期因果關係，MFM用於系統之短期監控。藉由組合此四項方法，我們嘗試發展一項包含三層檢驗門檻之方法，其可用於檢驗當外在環境改變時（例如，供應商之選擇、顧客偏好、產品選擇），整個供應鍊是否為可運作；是否可預期；以及其是否為穩定的。 “Information sharing” between the members of Extended Supply Chain is an important issue. When we talk about it, each member must use the same “language”. Before that, they should cognize the whole system with the same way first. We will apply the first two phases of the CWA (Cognitive Work Analysis) -- Work Domain Analysis and Control Task Analysis -- to achieve this objective. Then, we will focus the main issue on "supply chain configuration". We look the extended supply chain as a system, and try to develop a methodology, which make this system to be anticipated and stable. It’s difficult to understand and recognize the states of knowledge and the information processes of a system when the system is getting to complexity. Because of this reason, we use the methodologies, AH & DL, which extensively implemented in computer-based work in complex socio-technical system to grub the knowledge and the information processes in the system. Apply system dynamics (SD) to investigate the long-term causality of the ESC when the constitution of ESC changes. The MFM is used for short-term monitoring. By combining the four methods, we try to develop an approach which could provide the three levels of threshold to examine that if the supply chain is workable, anticipated, and stable when the environment of the supply chain changes (e.g., vendor choice, customer preferences, product choice).
