2. 1. Strategies for demand-driven supply chains : A decoupling thinking perspective

   Author : Fredrik Tiedemann; Joakim Wikner; Eva Johansson; Jenny Bäckstrand; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; demand driven; decoupling points; decoupling thinking; lead time; supply chain management; operations management; market segmentation; leagility; mass customization; supply chain visibility; postponement; financial performance; efterfrågedrivet; frikopplingspunkter; frikopplingstänkandet; ledtid; logistik; verksamhetsledning; segmentering; leagility; kundanpassning; transparens; senareläggning; räntabilitet;

   Abstract : In environments where customer requirements are constantly changing, such as for demand-driven manufacturing companies, the competition involves the ability to act and adapt to customer needs, sometimes even based on commitment from actual customer orders. In this context it is perhaps even more challenging to balance supply and demand. READ MORE

4. 2. Strategic lead-times and their implications on financial performance

   Author : Fredrik Tiedemann; Joakim Wikner; Eva Johansson; Jenny Bäckstrand; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; decoupling point; financial performance; manufacturing companies; new product development; production; purchasing; return on investment; ROI; strategic lead-time; finansiellt resultat; finansiella nyckeltal; frikopplingspunkt; inköp; lönsamhet; produktion; produktutveckling; strategiska ledtider; tillverkningsindustri;

   Abstract : The overall goal for manufacturing companies is to earn profit and increase shareholders’ value. To ensure that companies in fact are profitable, managers usually evaluate the company’s resources based on both financial and operational performance, to analyse if the resources are contributing with a financial return.

5. 3. Data-driven and real-time prediction models for iterative and simulation-driven design processes

   Author : Mohammad Arjomandi Rad; Joel Johansson; Fredrik Elgh; Alessandro Bertoni; Jönköping University; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Development lead time; Iterative design; Simulation-driven design; Design automation; Data-driven design; Artificial Intelligence;

   Abstract : The development of more complex products has increased dependency on virtual/digital models and emphasized the role of simulations as a means of validation before production. This level of dependency on digital models and simulation togetherwith the customization level and continuous requirement change leads to a large number of iterations in each stage of the product development process.

6. 4. Demand Flexibility for the Simultaneous Provision of Multiple Services : Tapping the Potential of Controllable Electric Loads for Frequency Reserves and Energy Arbitrage

   Author : Lars Herre; Lennart Söder; Qiuwei Wu; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aggregator; chance constrained optimisation; demand response; de-mand response provider; demand side management; frequency reserves; load control; stochastic optimization; aggregator; riskbegränsad optimering; efterfrågestyrning; leverantör av efterfrågesvar; efterfrågeflexibilitet; frekvensreserver; laststyrning; stokastisk optimering.; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Power systems with increasing shares of renewable energy sources require sufficient flexibility sources. One source of flexibility for future power systems is constituted by flexible electric loads. The concept of demand response captures the utilization of demand side flexibility to provide services to the power system. READ MORE

7. 5. A Method for Customer-driven Purchasing : Aligning Supplier interaction and Customer-driven manufacturing

   Author : Jenny Bäckstrand; Joakim Wikner; Eva Johansson; Martin Rudberg; Jönköping University; []
   Keywords : Customer‐driven purchasing; Supplier interaction; Customer‐driven manufacturing; Purchasing; Supply chain management;

   Abstract : The role of a purchaser has traditionally focused on acquiring standard items at the lowest possible cost. The ability to reduce unit cost has been the key performance indicator for purchasers. Most traditional purchasing strategies thus focus on optimizing this situation, focusing on the supplier interface only and not on customer value. READ MORE
