In the realm of machine learning (ML), the need for efficiency in training processes is paramount. The conventional first step in an ML workflow involves collecting data from various sources and merging them into a single table, a process known as materialization, which can introduce inefficiencies caused by redundant data. Factorized ML strives...

The workflow of a data science practitioner includes gathering information from different sources and applying machine learning (ML) models. Such dispersed information can be combined through a process known as Data Integration (DI), which defines relations between entities and attributes. When all information is combined in one source suited...

The work presented in this report is an attempt to allow density-based topology optimization algorithms to take into account machining costs when optimizing. To this end, and estimation model for the cost of 2.5-axis CNC milling was developed based on the principles of Design for Manufacturing.<br/>This estimation model was implemented in a...

Cost estimation of construction projects is still carried out using highly manual traditional tools and processes, which are deemed as inefficient and have a direct impact in the productivity levels of the industry. Building Information Modelling or BIM is changing the way projects are developed and has introduced some changes to cost estimation...

Many construction projects experience cost overruns (Flyvbjerg &amp; Holm, 2002), which is the difference between the estimated cost and the final costs of a project. In Design &amp; Build procured projects, the contractor is responsible for both designing and constructing the project (De Ridder, 2009). During the tender phase, the contractor...

Current literature shows that poor cost performance in projects has become routine. Research on cost performance has mostly focused on one of the involved parties, either the client or the contractor. Not many research efforts discuss the cost contingency performance of projects. This research discusses the cost performance and cost...

The current literature discusses the methods to estimate the costs and cost contingency. The literature also distinguishes "known unknowns" and "unknown unknowns" contingencies. Little is written, however, about the evolvement of total project cost estimates during the preconstruction phase of construction projects. Moreover, not many studies...

The construction industry faces problems in interoperability. Information is not easily interpreted nor accessed by participants. The insufficient level of interoperability occurs due to fragmentation between disciplines in the construction industry. To enhance interoperability, Building Information Modeling (BIM) formed a collaborative model...

Risk management is undoubtedly a precious component of the overall project management field. It assists in identifying, assessing and mitigating the uncertainties that are present in a project. These uncertainties affect important measures of a project, of which cost and schedule are the most prominent, and consequently put project success under...

It is desirable to predict construction cost with a high level of accuracy in the early phase to compare the budgetary with feasibility determinations. Additionally, it is required to be as quick as possible. However, the accuracy of the cost estimation depends on the design details which are extremely limited in such an early phase, rendering...

Accurate cost estimations are important for ship production companies such as Royal IHC. The research discussed is based on a feasibility study for a CBR cost estimation method. The current cost estimation method at IHC is a top-down price-to-win analogy cost estimation. This method uses mainly the weight of the ship as an input variable for the...

n an integrated aircraft design and analysis practice, Life Cycle Cost (LCC) is essential for decision making. The LCC of an aircraft is ordinarily partially estimated by emphasizing a specific cost type. However, an overview of the LCC including design and development cost, production cost, operating cost and disposal cost is not provided. This...

The design of reinforcement in concrete structures is a complex procedure, often resulting in inefficient designs. One possible solution to improve the design process and create more efficient designs is structural optimisation. This Master’s Thesis focusses on the development of a technique for optimisation of reinforcement in 3D concrete...

There is very little publicly available data about the building cost of inland ships, especially for ships that have dimensions that differ significantly from those of common ships. Also, no methods to determine the building cost of inland ships are described in literature. In this paper, a method to estimate the building cost of inland ships is...

Problem definition The city Mar del Plata has one of Argentina's largest ports and biggest seaside beach resort. After the construction of the port, a steadily growing sandbank appeared in the port entrance and considerable erosion occurred on the northern beaches. To warrant the accessibility of the port, frequent maintenance dredging is needed...

Competitive aircraft box structures are a perfect compromise between weight and price. The conceptual design process of these structures is a typical Multidisciplinary Design and Optimization effort, normally conducted by human engineers. The iterative nature of MDO turns development into a long and costly process. Knowledge-Based Engineering...

This thesis studies cost estimation and investment decisions under cost uncertainty of large construction projects. The combination of these two topics intends to satisfy the Master’s theses of Civil Engineering at the Delft University of Technology and Quantitative Finance (Econometrics) at the Erasmus University Rotterdam. The first part...

In the today's market of microcontrollers and FPGAs, there are so much different makes and models that making the right choice for a hardware platform for an electronics design is impossible. The spectrum is so wide that an electronics designer is unable to make a good choice for the best microcontroller or FPGA for his/her design based on the...

In het verleden is gebleken, dat de door Rijkswaterstaat gemaakte ramingen tijdens de levensloop van een project (van voorfase tot realisering) een stijgende tendens vertoonden. Mede op verzoek van de Tweede Kamer heeft het Ministerie van Verkeer en Waterstaat een onderzoek verricht naar de oorzaken van deze ramingsstijgingen. Op basis van de...
