Abstract
Assessment of novel temperature monitoring systems for improving cold chain
management in meat supply chains
The objective of this thesis has been to develop a concept to assess temperature monitoring
systems. In particular, the ability of such systems to improve cold chain management has
been investigated. The improvement potential has been considered taking into account the
scoring and ranking of available systems for different meat supply chains.
The concept is based on several empirical and experimental studies which are concerned
with four research questions. The detailed examination of a large variety of intra- and inter-
organizational temperature monitoring systems, as well as solutions, followed the
characterization of key functionalities of these systems. Due to the characterization of
implementation challenges, the necessary requirements in customer-supplier relationships in
cold supply chains could be established.
Taking these requirements into account, the importance of a three-dimensional (technical,
organizational and functional) view of the improvement of cold chain management could be
derived, resulting in a three-dimensional generic model. The importance of this three-
dimensional view has been investigated in a long-term field trial in a poultry supply chain
using Time-Temperature-Indicators (TTIs) as an example. In total, comprehensive data sets
from ten “Temperature mappings”, six field trials with Time-Temperature-Indicators (TTIs)
and two field trials with RFIDs with a temperature sensor and results from 20 expert
discussions were available for the derivation of the assessment concept. 11 companies
involved in poultry, fish, pork, beef and cooked ham supply chains on a (German) national,
international and global scale have been involved in the study.
Based on the results, a concept for assessing temperature monitoring solutions is been
proposed. It is defined as the “Multi-criteria Decision Aid - Cold Chain Management (MCDA-
CCM)” - concept. It is a combination of five levels and five columns which contain the
respective phases, steps and elements of the process concept. For the process of the
assessment, four steps have been defined – Requirement determination (1), Scoring process
(2), Calculation (3) and Ranking (4) – divided into the phases “CCM requirement creation”
and “Assessment and Decision”. In the first step the ‘‘Three-dimensional generic model” is
proposed for determination and categorization of 14 cold chain management relevant
technical, organizational and functional criteria. By using a “Scoring model” (step 2), the
weighting of the criteria can be conducted. In the final two steps, the Multi-Criteria Decision
Aid method PROMETHEE (Preference Ranking Organization Method for Enrichment
Evaluation) permits the calculation of “outranking net flows” (step 3) enabling the ranking of a
finite number of temperature monitoring alternatives (step 4). The user-orientated
assessment concept facilitates decision making so as to ascertain the best temperature
monitoring solution for specific application cases.
