  1. Artisan Task 1.3 Mapping of enterprise data ...@dobi.it

  2. Agenda • Mapping to Data Structure – Scenarios • Structure of a textile ERP • DS-S 1: online monitoring • DS-S 2: mapping to production orders • DS-S 3: model for produc groups: total • DS-S 4: time profiles by group • DS-S 5: allocation for energy consumption • DS-S 6: allocation of embodied energy

  3. Mapping to Data Structure – Scenarios • Scenarios were agreed in the kick off meeting • Each scenario defines a data structure • Seven of them defined • They cover different areas in energy consumption • Main objectives of Task 1.3 • Map existing data to scenarios • Showing the structure of textile companies • Explaining if and where data are available

  4. Structure of a textile ERP • Textile companies are not all the same • Weaving mills • Spinning mills • Third party finishing / dyeing • Others... • The main concepts are similar • Generic structure • We will ignore thousands of customizations

  5. Structure of a textile ERP Articles may be fabrics, twisted or simple yarns, raw material Order rows will feed the production management module Bill of Material says which yarns compose a fabric, which raw material composes a yarn The batch table contains all pieces in production The actual Workflow and Bill of Material are updated while processing A generic workflow is associated to the article

  6. DS-S 1: online monitoring Introduce or dispose heat ? Heat suppliers Heat dispersors heating The plant department department department engines walls lamps windows department office office air exchange refrigerators dryers

  7. DS-S 1: online monitoring Processes (examples) Transformation from Yarn to Fabric Wet finishing Pieces dyeing Raising Stenter Dry finishing Final control and shipping Department Ind. energy Process Machine 1 (loom) Stage 1 (weaving) Direct energy Machine 2 Stage 2 Direct energy Machine 3 Stage 3 Direct energy

  8. DS-S 1: online monitoring

  9. DS-S 2: mapping to production orders • Total energy splitted in • Direct Energy (used in production) • Indirect Energy (used in the infrastructure) E(U) = EDir(U) + EInd(U) • Direct Energy: • Sum energy of stages: Etot = E(f1)+ E(f2)+...+ E(fn) • Divide by total amount: EDir(U) = Etot / Qta • Indirect energy • [EInd(u)] = (EInd department/working time)*Unit production time

  10. DS-S 3: model for product group: total • Divide articles in groups: • Begin from commercial groups defined in ERP • Similar stages • Similar machines • Refine grouping by «macro process» • Similar stages in process • Example: group products having similar stages in «textile transformation from yarn to fabric»

  11. DS-S 4: time profiles by group • Compute the average time of permanence of each macro process for a unit of product:

  12. DS-S 5: allocation for energy consumption Generic model of energy consumption. Energy provider Energy consumer The workflow, a set of stages, generate the energy consumption Tells the provider how much energy is needed or stops the consumer

  13. DS-S 6: allocation of embodied energy • Energy used for maintenance and emissions • Solid emissions • Fibers • Plastic • Packaging • ... • Liquid emissions • Water • Oil • Chemical products • ... • Gas emissions • CO2

  14. Q & A
