This FAO manual on Risk based imported food control aims to support competent authorities in improving the effectiveness of the control measures they are overseeing, based on an analysis of their specific country situation. It discusses the different types of approach to managing risks related to imported food, and provides concrete illustrations of how Codex guidelines can be implemented in different ways. While respecting the principles, guidance and objectives agreed by the Codex Alimentarius Commission, different options for control measures can be selected and combined to implement a coherent set of import controls to best fit the needs of each country. Different examples, as implemented by a number of countries, are provided to show that there are often several options to reach a common goal. It also provides insights on the legal and institutional frameworks, as well as on the necessary support services to effectively implement risk based food controls.

Based on course-tested material, this rigorous yet accessible graduate textbook covers both fundamental and advanced optimization theory and algorithms. It covers a wide range of numerical methods and topics, including both gradient-based and gradient-free algorithms, multidisciplinary design optimization, and uncertainty, with instruction on how to determine which algorithm should be used for a given application. It also provides an overview of models and how to prepare them for use with numerical optimization, including derivative computation. Over 400 high-quality visualizations and numerous examples facilitate understanding of the theory, and practical tips address common issues encountered in practical engineering design optimization and how to address them. Numerous end-of-chapter homework problems, progressing in difficulty, help put knowledge into practice. Accompanied online by a solutions manual for instructors and source code for problems, this is ideal for a one- or two-semester graduate course on optimization in aerospace, civil, mechanical, electrical, and chemical engineering departments.
