 note = {本研究では,多工程連続作業から構成される部品組み立て作業に対して,作業の実績収集と分析を行うためのデジタルマニュアル表示システムの構築と運用例を示す.はじめに,デジタルアニュアルの特徴を分類し,本研究で開発する実績収集と分析を目的とするデジタルマニュアル表示システムの位置づけを行う.そして,デジタルマニュアル表示システムによって工程ごとに収集される作業時間から,動作分析結果と関連付けることで同一あるいは類似製品の作業時間の算出法を提案する.提案法では,動作分析から算出される作業時間からの乖離,および作業者間での乖離が生じる要因として製品構造,作業者の姿勢を位置決め精度を考慮し,ニューラルネットワークにより作業時間を補正する.開発したシステムを実作業に適用し,デジタルマニュアル表示システムによる工程作業の評価例と作業時間の見積りの提案法の有効性を示す.Many factories introduce assembly processes in which a single worker performs multi-step operations to complete products for multi-item, small-lot production. This type of assembly process results in reductions in production lead-time and inventories in the process. However, since workers continuously control operating processes composed of different operations to complete different types of products, operation error caused by the worker is possible. To reduce operation errors, a digital manual presentation system is introduced and is used to instruct workers on continuous operation procedures for products in actual factories. The presentation system naturally involves a function to collect operation time in the assembly process. In this paper, we focus on a function to collect operation time in the presentation system and develop a digital manual presentation system for analyzing operation properties using data collected from multi-step assembly tasks. First, we show the concept of a developed system and a data structure in which relations to operations and worker motions are included. Then, three types of operation difficulties are introduced and a method to estimate operation time is proposed as a function of the manual presentation system. The proposed method generates operation times using an evaluation of operation difficulties caused by worker's motions. The developed system is applied to an actual assembly process, and relations between operation properties and operation difficulties are analyzed from the operation times collected in the system. Analyzed results show that the operation difficulties cause operation times to increase and the amount of time increased depends on a worker's skill level. Moreover, the results show that the proposed method to estimate operation time generates an approximate operation time for the manufacture of new products.},
