PROBLEM TO BE SOLVED: To prevent deterioration of a production cost due to a decrease in a profit rate due to reduction in quality evaluation of a dried laver production facility, an increase in energy cost due to deterioration in an energy consumption basic unit, and an increase in a maintenance cost required for maintenance work under an adverse environment of midnight, a midwinter season or the like.SOLUTION: In a system for supporting the maintenance of the quality of a dried laver production device or the retroaction of a quality deterioration cause, supporting maintenance work, and supporting reduction of an energy cost price in production, element information comprising state data of dried laver quality due to information confirmed by a sensor provided in the device and a laver producer, data of an operation state sensor of a management apparatus, data of a natural environment sensor, and control data adjusted for quality maintenance by the laver producer as one set is stored, and partial information for associating a data group with maintenance information of the management apparatus is found. The data group is obtained by being associated with data having a cause-effect relationship to a state of laver quality by multivariable analysis.SELECTED DRAWING: Figure 2【課題】乾燥海苔製造設備の品質評価の低下による利益率の低下、エネルギー消費原単位の悪化によるエネルギー費の上昇、深夜及び厳寒期等の劣悪な環境下でのメンテナンス作業にかかる保守費の上昇による製造コストの悪化を防止する。【解決手段】乾燥海苔製造装置の品質の維持又は品質低下原因の遡及を支援し、メンテナンス作業を支援し、製造におけるエネルギー原価の低減を支援するシステムにおいて、装置に設けたセンサ及び海苔製造者が確認した情報による乾燥海苔品質の状況データ、管理機器の運転状況センサのデータ、自然環境センサのデータ、海苔製造者が品質維持のために調整した制御データを１セットとする要素情報を記憶し、海苔品質の状況と因果関係があるものを多変量解析によって、関連付けたデータ群を、管理機器のメンテナンス情報と関連する部分情報を見いだす。【選択図】図２
