Drivers and Barriers of Collaboration in the Value Chain of Paperboard-Packed Consumer Goods

Value chain collaboration has been a prevailing topic for research, and there is a constantly growing interest in developing collaborative models for improved efficiency in logistics. One area of collaboration is demand information management, which enables improved visibility and decrease of inventories in the value chain. Outsourcing of non-core competencies has changed the nature of collaboration from intra-enterprise to cross-enterprise activity, and this together with increasing competition in the globalizing markets have created a need for methods and tools for collaborative work. The retailer part in the value chain of consumer packaged goods (CPG) has been studied relatively widely, proven models have been defined, and there exist several best practice collaboration cases. The information and communications technology has developed rapidly, offering efficient solutions and applications to exchange information between value chain partners. However, the majority of CPG industry still works with traditional business models and practices. This concerns especially companies operating in the upstream of the CPG value chain. Demand information for consumer packaged goods originates at retailers' counters, based on consumers' buying decisions. As this information does not get transferred along the value chain towards the upstream parties, each player needs to optimize their part, causing safety margins for inventories and speculation in purchasing decisions. The safety margins increase with each player, resulting in a phenomenon known as the bullwhip effect. The further the company is from the original demand information source, the more distorted the information is. This thesis concentrates on the upstream parts of the value chain of consumer packaged goods, and more precisely the packaging value chain. Packaging is becoming a part of the product with informative and interactive features, and therefore is not just a cost item needed to protect the product. The upstream part of the CPG value chain is distinctive, as the product changes after each involved party, and therefore the original demand information from the retailers cannot be utilized as such – even if it were transferred seamlessly. The objective of this thesis is to examine the main drivers for collaboration, and barriers causing the moderate adaptation level of collaborative models. Another objective is to define a collaborative demand information management model and test it in a pilot business situation in order to see if the barriers can be eliminated. The empirical part of this thesis contains three parts, all related to the research objective, but involving different target groups, viewpoints and research approaches. The study shows evidence that the main barriers for collaboration are very similar to the barriers in the lower part of the same value chain; lack of trust, lack of business case and lack of senior management commitment. Eliminating one of them – the lack of business case – is not enough to eliminate the two other barriers, as the operational model in this thesis shows. The uncertainty of the future, fear of losing an independent position in purchasing decision making and lack of commitment remain strong enough barriers to prevent the implementation of the proposed collaborative business model. The study proposes a new way of defining the value chain processes: it divides the contracting and planning process into two processes, one managing the commercial parts and the other managing the quantity and specification related issues. This model can reduce the resistance to collaboration, as the commercial part of the contracting process would remain the same as in the traditional model. The quantity/specification-related issues would be managed by the parties with the best capabilities and resources, as well as access to the original demand information. The parties in between would be involved in the planning process as well, as their impact for the next party upstream is significant. The study also highlights the future challenges for companies operating in the CPG value chain. The markets are becoming global, with toughening competition. Also, the technology development will most likely continue with a speed exceeding the adaptation capabilities of the industry. Value chains are also becoming increasingly dynamic, which means shorter and more agile business relationships, and at the same time the predictability of consumer demand is getting more difficult due to shorter product life cycles and trends. These changes will certainly have an effect on companies' operational models, but it is very difficult to estimate when and how the proven methods will gain wide enough adaptation to become standards.

Putkien päittäishitsaaminen orbitaali-TIG-hitsauksella

Tämän kandidaatintyön tavoitteena oli esitellä orbitaali-TIG-hitsauksen käyttämistä putkien päittäishitsaamiseen. Työssä esitellään Suomesta saatavia orbitaali-TIG-laitteita ja TIG-hitsausprosessi pääperiaatteiltaan sekä prosessin käyttämistä orbitaalihitsaukseen. Myös orbitaali-TIG-hitsauksen tuottavuuteen ja laatuun liittyviä asioita käydään läpi. Suomesta saatavilla olevista laitteista valittiin toiminnallisten mittojen kannalta sopivimmat kandidaatintyötä varten suunniteltuun ripaputkilämmönvaihtimen hitsaukseen. Työ on pääasiallisesti tehty kirjallisuustutkimuksena käyttäen apuna orbitaalilaitteistojen valmistajien ja jälleenmyyjien haastatteluja. Kirjalliset lähteet koostuvat kotimaisesta ja kansainvälisestä hitsauksen alan kirjallisuudesta ja teksti on pyritty sitomaan yhteen käyttäen useaa eri lähdettä. Laitekohtaiset tiedot saatiin laitevalmistajien tuotetiedotteista ja sähköpostihaastatteluna laitteiden jälleenmyyjiltä ja laitevalmistajilta. Suomessa orbitaali-TIG-laitteita maahantuo ja jälleenmyy Masino Welding Oy ja Suomen Teknohaus Oy. Suomessa laitteita valmistaa Kemppi Oy, jonka orbitaalilaitteilla on useita jälleenmyyjiä. Masino Welding Oy myy saksalaisia Orbitalum GmbH:n laitteita ja Suomen Teknohaus Oy ranskalaisia Polysoude S.A.S.:n laitteita. Näiden laitevalmistajien joukosta suunnitellun ripaputkilämmönvaihtimen hitsaukseen soveltuu Orbitalumilta ja Polysoudelta yhdet sekä Kempiltä kaksi umpipihtimallista orbitaalihitsauspäätä. Orbitaali-TIG-hitsauslaitteissa virtalähteet ovat kehittyneet eniten vuosien aikana ja eri laitevalmistajien laitteistojen erot ovat pääasiassa virtalähteisiin liittyviä. Ripaputkilämmönvaihtimen hitsaamiseen sopivin hitsauspäämalli on umpipihti, sillä lämmönvaihtimen päädyt ovat hyvin ahtaita ja umpipihdit ovat orbitaalihitsauspäistä kaikkein kompakteimmat. Suomessa orbitaali-TIG-laitteita ei ole kauheasti tarjolla ja laitteiden markkinointi on jossain määrin kannattamatonta. Orbitaalihitsaus on kuitenkin varteenotettava vaihtoehto TIG-käsinhitsaukselle, jos hitsataan paljon samankaltaisia hitsejä.

RCOS: Real time context sharing across a fleet of smart mobile devices

Today, biodiversity is endangered by the currently applied intensive farming methods imposed on food producers by intermediate actors (e.g.: retailers). The lack of a direct communication technology between the food producer and the consumer creates dependency on the intermediate actors for both producers and the consumers. A tool allowing producers to directly and efficiently market produce that meets customer demands could greatly reduce the dependency enforced by intermediate actors. To this end, in this thesis, we propose, develop, implement and validate a Real Time Context Sharing (RCOS) system. RCOS takes advantage of the widely used publish/subscribe paradigm to exchange messages between producers and consumers, directly, according to their interest and context. Current systems follow a topic-based model or a content-based model. With RCOS, we propose a context-awareness approach into the matching process of publish/subscribe paradigm. Finally, as a proof of concept, we extend the Apache ActiveMQ Artemis software and create a client prototype. We evaluate our proof of concept for larger scale deployment.
