A conceptual framework for crop-based agri-food supply chain characterization under uncertainty

[EN] Crop-based Agri-food Supply Chains (AFSCs) are complex systems that face multiple sources of uncertainty that can cause a significant imbalance between supply and demand in terms of product varieties, quantities, qualities, customer requirements, times and prices, all of which greatly complicate their management. Poor management of these sources of uncertainty in these AFSCs can have negative impact on quality, safety, and sustainability by reducing the logistic efficiency and increasing the waste. Therefore, it becomes crucial to develop models in order to deal with the key sources of uncertainty. For this purpose, it is necessary to precisely understand and define the problem under study. Even, the characterisation process of this domains is also a difficult and time-consuming task, especially when the right directions and standards are not in place. In this chapter, a Conceptual Framework is proposed that systematically collects those aspects that are relevant for an adequate crop-based AFSC management under uncertainty.Authors of this publication acknowledge the contribution of the Project 691249, RUC-APS "Enhancing and implementing Knowledge based ICT solutions within high Risk and Uncertain Conditions for Agriculture Production Systems" (www.ruc-aps.eu), funded by the European Union under their funding scheme H2020-MSCA-RISE-2015Alemany Díaz, MDM.; Esteso, A.; Ortiz Bas, Á.; Hernández Hormazabal, JE.; Fernández, A.; Garrido, A.; Martin, J....

Automated Planning of Concrete Joint Layouts with 4D-BIM

Concrete pouring represents a major critical path activity that is often affected by design limitations, structural considerations and on-site operational constraints. As such, meticulous planning is required to ensure that both the aesthetic and structural integrity of joints between cast in-situ components is achieved. Failure to adequately plan concrete pouring could lead to structural defects, construction rework or structural instability, all having major financial implications. Given the inherent complexity of large-scale construction projects, the ‘manual planning’ of concrete pouring is a challenging task and prone to human errors. Against this backdrop, this study developed 4D Building Information Management (BIM) approach to facilitate automated concrete joint positioning solution (as a proof of concept) for design professionals and contractors. The study first developed structural model in Revit, then extracted spatial information regarding all construction joints and linked them to dynamic Microsoft (MS) Excel and Matlab spreadsheets using integration facilitated by Dynamo software. Midspan points of each beam as well as floor perimeter information were gathered via codes developed in MS Excel macros. Based on the Excel outputs, Matlab programming was used to determine best concreating starting points and directions, and daily allowed concrete volume, considering limitations due to cold joints. These information were then pushed back to Revit via Dynamo in order to develop daily concrete scheduling. The developed automated programme framework offers a cost-effective and accurate methodology to address the limitations and inefficiencies of traditional methods of designing construction joints and planning pours. This framework extends the body of knowledge by introducing innovative solutions to integrate structural design considerations, constructional procedures and operational aspects for mitigating human error, and providing a novel, yet technically sound, basis for further application of BIM in structural engineering

Manufacturing and Supply Chain Flexibility: Building an Integrative Conceptual Model Through Systematic Literature Review and Bibliometric Analysis

The purpose of this study is twofold: first, to establish the current themes on the topic of manufacturing and supply chain flexibility (MSCF), assess their level of maturity in relation to each other, identify the emerging ones and reflect on how they can inform each other, and second, to develop a conceptual model of MSCF that links different themes connect and highlight future research opportunities. The study builds on a sample of 222 articles published from 1996 to 2018 in international, peer-reviewed journals. The analysis of the sample involves two complementary approaches: the co-word technique to identify the thematic clusters as well as their relative standing and a critical reflection on the papers to explain the intellectual content of these thematic clusters. The results of the co-word analysis show that MSCF is a dynamic topic with a rich and complex structure that comprises five thematic clusters. The value chain, capability and volatility clusters showed research topics that were taking a central role in the discussion on MSCF but were not mature yet. The SC purchasing practices and SC planning clusters involved work that was more focused and could be considered more mature. These clusters were then integrated in a framework that built on the competence–capability perspective and identified the major structural and infrastructural elements of MSCF as well as its antecedents and consequences. This paper proposes an integrative framework helping managers keep track the various decisions they need to make to increase flexibility from the viewpoint of the entire value chain

Health and Safety Perception of Workers in Turkey: A Survey of Construction Sites

This study reports the general health and safety (HS) conditions in the Turkish construction industry from the perspective of construction labor. Toward this aim, a questionnaire survey was carried out with 800 workers employed in 32 construction projects in Turkey. Contractors were found to neglect their legal liabilities in paying workers’ insurance premiums. Also, they overlooked safety training and were reluctant to hiring physicians at construction sites and investing in personal protective equipment (PPE). As the real constructors of projects, workers did not attach adequate importance to occupational training. In addition, they were not willing to use some PPE. Key participants of HS affairs such as workers, contractors, unions, and government should comprehend their drawbacks to overcome the current dangerous view of the industry. In this regard, related government bodies should compel contractors and workers to adapt to the relatively new regulations on occupational HS

An Important Genetic Resource for Turkey: Cherry Laurel (Laurocerasus officinalis Roemer)

2nd International Symposium on Pomegranate and Minor - Including Mediterranean - Fruits (ISPMMF) -- JUN 23, 2009 -- Dharwad, INDIAWOS: 000323738600037Karayemis (Prunus laurocerasus L.) is included in the Rosaceae family, Prunoideae sub-family, Prunus genus. Like for many other fruits, Anatolia is the origin of karayemis. This species is naturally found in Caucasia, East Black Sea, North and East Marmara and Taurus mountains. The height of the karayemis plant is 2-6 m, and evergreen. The flower of karayemis is white in color and the fruit is black and red in color just like sweet cherry. Fruits are connected to clusters which are 10-20 cm long. In growing areas of Turkey (East Black Sea region), it is consumed by the people as a fresh fruit, also evaluated as dried, pickled, jam and stewed fruit. Because of being an evergreen plant, it is used as an ornamental plant in parks, also having many chemicals in young shoots, fruits and seeds it is used in pharmacology extensively. Except for the Black Sea region, karayemis is a new fruit species for Turkey and the world. Recently new fruits are always interesting for the world markets and for our country and have high prices such as kiwifruit and some tropical fruits. In our country, the origin of karayemis, important economic advantages will be gained by introducing karayemis to inner and outer markets. Such as in other fruit species originated in our country, also in karayemis, most important genetic resources are being depleted. Therefore, to preserve these resources, precautions have to be taken immediately.Int Soc Hort Sci (ISHS

Quality function deployment in the speculative house-building market: How to satisfy high-income customers

This paper presents a study that reports a detailed process of 'quality function deployment', considering an ultra-luxury villa project. It is based on a questionnaire survey that was applied to 42 residents and seven top managers. The results highlight real expectations of high-income residents. Residents were not satisfied with the 'sauna', 'sports areas', and 'fitness centre' despite the fact that these were among the least important expectations. However, residents were satisfied with the 'security of the complex', 'architectural design', and 'quality of the end-products'. If some expectations (i.e. 'areas for common use', 'playing areas for children', and 'quality of the end-products') achieve better technical standards in the next projects, demand for luxury residences will likely be improved. Consequently, 25 expectations and corresponding findings constitute a preliminary framework for an expectations agenda for such projects for builders who wish to improve marketing practices. © 2015 Taylor & Francis

Classification of construction firms in Turkey by using miles and snow’s Typology

Although strategic management is not common among construction firms, it was argued that construction firms develop strategies to maintain in the competitive environment and that they can be categorized according to their strategies, even if they are not managed formally. Because construction firms’ strategies are specific and they are unwilling to share them, it is difficult to determine these strategies clearly. In this regard, instead of determining their strategies, it was aimed to categorize them according to Miles and Snow’s Strategy Typology. Toward this aim, 50 large-scale construction firms in Turkey were surveyed by a questionnaire. In this context, Miles and Snow’s Typology was first investigated, and possible goals of each strategic group were determined. Then, a SWOT analysis was applied to firms to determine their current positions in the market, and their primary goals were asked. The results revealed that construction firms with the same goals show similar characteristics and thus can be categorized as defenders, prospectors, and analyzers, according to Miles and Snow’s Typology. © 2015, Kauno Technologijos Universitetas.
